Language tags for communities/sites

[Nutomic]

• [x] allowed languages are shown in site/community sidebar (user languages are not publicly shown)
• [x] admins/mods can edit languages for sites/communities (using the same input as in user profile)
• [ ] during post/comment creation, language selection is limited to intersection between user languages and community languages. If that leaves only a single language, hide the input field (same logic as here)

see #771

This is done now.

Where is the code for this?

I'll check again today

I'm not exactly sure how I'm going to solve the "limit language selection when creating a post or comment" one... because discussion_languages only comes back from GetCommunity. Just too many complications to handle right now, so I'm just going to limit it to their user language, and let the backend reject incorrect community languages. Scenarios like:

• What if the persons replying from their inbox, or from someone's profile page? That'd require fetching tons of communities.
• On the CreatePost page, they have a list of communities, but it doesn't have the languages for each one. That would require an additional fetch.
• The post page doesn't have community_languages either, just the community_view. So we'd have to add that to the API.

Well we can add discussion_languages to those endpoints where its missing. Or rely on user languages for now and do some cleanup later.

What currently works:

• Setting site languages
• Setting profile languages
• Setting community languages
• Create community shows all site langs

What doesn't work / is halfway broken:

• Saving the community won't live-update the community langs
• Saving the site won't live-update the site langs
• Creating a post or comment only does the intersection of the site and your langs, not the community langs. This is going to be a difficult one, as many areas of the UI are multi-community, like inbox, profile, etc. That would require selecting a community, then fetching it to get its langs.
• The language dropdown should be moved into the options bar for the markdown fields, because right now it takes up too much space.

Since Mastodon and Akkoma (Pleroma fork) seem to have build in translators now (using Libretranslate!) I think it might be good to see how they tag the language of a post and make this compatible.

This is already implemented.
