Rework markup link rendering (#26745)
Fixes #26548

This PR refactors the rendering of markup links. The old code uses
`strings.Replace` to change some urls while the new code uses more
context to decide which link should be generated.

The added tests should ensure the same output for the old and new
behaviour (besides the bug).

We may need to refactor the rendering a bit more to make it clear how
the different helper methods render the input string. There are lots of
options (resolve links / images / mentions / git hashes / emojis / ...)
but you don't really know what helper uses which options. For example,
we currently support images in the user description which should not be
allowed I think:

<details>
  <summary>Profile</summary>

Make cross-reference issue links work in markdown documents again (#28682)
In #26365 issue references were disabled entirely for documents,
intending to match GitHub behavior. However cross-references do appear
to work in documents on GitHub.

This is useful for example to write release notes in a markdown document
and reference issues. While the simpler syntax may create links when not
intended, hopefully the cross-reference syntax is unique enough to avoid
it.

Fix the issue ref rendering for wiki (#28556)
Fix #28526, regression of 
* #26365

(although the author of #26365 has recent activities, but there is no
response for the regression, so I proposed this quick fix and keep the
fix simple to make it easier to backport to 1.21)

Do not highlight #number in documents (#26365)
- Currently the post processing will transform all issue indexes (such as `#6`) into a clickable link.
- This makes sense in an situation like issues or PRs,
where referencing to other issues is quite common
and only referencing their issue index is an handy and efficient way to do it.
- Currently this is also run for documents
(which is the user profile and viewing rendered files),
but in those situations it's less common to reference issues by their index and instead could mean something else.
- This patch disables this post processing for issue index for documents. Matches Github's behavior.
- Added unit tests.
- Resolves https://codeberg.org/Codeberg/Community/issues/1120

Same on GitHub:

`dir=auto` enables a browser heuristic that sets the text direction
automatically. It is the only way to get automatic text direction.

Append (comment) when a link points at a comment rather than the whole issue (#23734)
Close #23671 

For the feature mentioned above, this PR append ' (comment)' to the
rendered html if it is a hashcomment.
After the PR, type in the following

```
pull request from other repo:
http://localhost:3000/testOrg/testOrgRepo/pulls/2

pull request from this repo:
http://localhost:3000/aaa/testA/pulls/2

issue comment from this repo:
http://localhost:3000/aaa/testA/issues/1#issuecomment-18

http://localhost:3000/aaa/testA/pulls/2#issue-9

issue comment from other repo:
http://localhost:3000/testOrg/testOrgRepo/pulls/2#issuecomment-24

http://localhost:3000/testOrg/testOrgRepo/pulls/2#issue
```
Gives:

Other than the above feature, this PR also includes two other changes:

1 Right now, the render of links from file changed tab in pull request
might not be very proper, for example, if type in the following. (not
sure if this is an issue or design, if not an issue, I will revert the
changes). example on
[try.gitea.io](https://try.gitea.io/HesterG/testrepo/pulls/1)
```
https://try.gitea.io/HesterG/testrepo/pulls/1/files#issuecomment-162725
https://try.gitea.io/HesterG/testrepo/pulls/1/files
```
it will render the following 
<img width="899" alt="截屏2023-03-24 15 41 37"
src="https://user-images.githubusercontent.com/17645053/227456117-5eccedb7-9118-4540-929d-aee9a76de852.png">

In this PR, skip processing the link into a ref issue if it is a link
from files changed tab in pull request

After:
type in following
```
hash comment on files changed tab:
http://localhost:3000/testOrg/testOrgRepo/pulls/2/files#issuecomment-24

files changed link:
http://localhost:3000/testOrg/testOrgRepo/pulls/2/files
```
Gives

2 Right now, after editing the comment area, there will not be tippys
attached to `ref-issue`; and no tippy attached on preview as well.
example:

In this PR, in frontend, make sure tippy is added after editing the
comment, and to the comment on preview tab

Add context when rendering labels or emojis (#23281)
This branch continues the work of #23092 and attempts to rid the
codebase of any `nil` contexts when using a `RenderContext`.

Anything that renders markdown or does post processing may call
`markup.sha1CurrentPatternProcessor()`, and this runs
`git.OpenRepository()`, which needs a context. It will panic if the
context is `nil`. This branch attempts to _always_ include a context
when creating a `RenderContext` to prevent future crashes.

Refactor legacy unknwon/com package, improve golangci lint (#19284)
The main purpose is to refactor the legacy `unknwon/com` package.
1. Remove most imports of `unknwon/com`, only `util/legacy.go` imports the legacy `unknwon/com`
2. Use golangci's depguard to process denied packages
3. Fix some incorrect values in golangci.yml, eg, the version should be quoted string `"1.18"`
4. Use correctly escaped content for `go-import` and `go-source` meta tags
5. Refactor `com.Expand` to our stable (and the same fast) `vars.Expand`, our `vars.Expand` can still return partially rendered content even if the template is not good (eg: key mistach).
