Deprecate Mirror Repositories

From a convo with @FabianLars and @lucasfernog:

> I would like to deprecate the mirrors. The v2 plugins have support for withGlobalTauri and pnpm supports sub folders in git dependencies now (the latter would require us to commit the dist files).

> let's start archiving them with a link to the plugins repo

This has some steps in no particular order:

- [ ] Archive Mirrors
- [ ] Add link to plugin repo
- [ ] Setup workflow to build and commit dist files
- [ ] TBD

What else would be required to start the transitioning @FabianLars ?
