Lazy-load TimeAgo locales (#2094)

1. new translation docs
2. lazy-load TimeAgo locales (used for "x min ago" messages). This 1.
reduces size and 2. provides all languages without adding them manually.
3. Remove DayJS locales, they're unused.

 # Translations
 
-Woodpecker uses [Vue I18n](https://vue-i18n.intlify.dev/) as translation library, thus you can easily translate the web UI into your language. Therefore, copy the file `web/src/assets/locales/en.json` to the same path with your language's code and `.json` as name.
+To translate the web UI into your language, we have [our own Weblate instance](https://translate.woodpecker-ci.org/). Please register there and translate Woodpecker into your language. **We won't accept PRs changing any language except English.**
-Then, translate content of this file, but only the values:
 
-```json
+<a href="https://translate.woodpecker-ci.org/engage/woodpecker-ci/">
-{
+  <img src="https://translate.woodpecker-ci.org/widgets/woodpecker-ci/-/ui/multi-blue.svg" alt="Translation status" />
-  "dont_translate": "Only translate this text"
+</a>
-}
-```
 
-To add support for time formatting, import the language into two files:
+Woodpecker uses [Vue I18n](https://vue-i18n.intlify.dev/) as translation library.
-
-1. `web/src/compositions/useDate.ts`: Just add a line like `import 'dayjs/locale/en';` to the first block of `import` statements and replace `en` with your language's code.
-2. `web/src/utils/timeAgo.ts`: Add a line like `import en from 'javascript-time-ago/locale/en.json';` to the other `import`-statements and replace both `en`s with your language's code. Then, add the line `TimeAgo.addDefaultLocale(en);` to the other lines of them, and replace `en` with your language's code.
-
-Then, the web UI should be available in your language. You should open a pull request to our repository to get your changes into the next release.
