[GITEA] Allow changing the repo Wiki branch to main Previously, the repo wiki was hardcoded to use `master` as its branch, this change makes it possible to use `main` (or something else, governed by `[repository].DEFAULT_BRANCH`, a setting that already exists and defaults to `main`). The way it is done is that a new column is added to the `repository` table: `wiki_branch`. The migration will make existing repositories default to `master`, for compatibility's sake, even if they don't have a Wiki (because it's easier to do that). Newly created repositories will default to `[repository].DEFAULT_BRANCH` instead. The Wiki service was updated to use the branch name stored in the database, and fall back to the default if it is empty. Old repositories with Wikis using the older `master` branch will have the option to do a one-time transition to `main`, available via the repository settings in the "Danger Zone". This option will only be available for repositories that have the internal wiki enabled, it is not empty, and the wiki branch is not `[repository].DEFAULT_BRANCH`. When migrating a repository with a Wiki, Forgejo will use the same branch name for the wiki as the source repository did. If that's not the same as the default, the option to normalize it will be available after the migration's done. Additionally, the `/api/v1/{owner}/{repo}` endpoint was updated: it will now include the wiki branch name in `GET` requests, and allow changing the wiki branch via `PATCH`. Signed-off-by: Gergely Nagy <forgejo@gergo.csillger.hu> (cherry picked from commit d87c526d2a313fa45093ab49b78bb30322b33298)
