Language team information

### Describe the problem

Damned Lies which GNOME is using has this: https://l10n.gnome.org/teams/fr/. Can we have something similar in Weblate?

### Solution brainstorm

Target this feature to dedicated instances only and extend https://translate.fedoraproject.org/languages/fr/.

### Describe alternatives you have considered

We could probably expose this information from teams as well to work on the project level. This would make it possible to work on shared sites like Codeberg or Hosted Weblate, but the discoverability of that would be much lower (simply because there could potentially be PROJECT * LANGUAGE of teams).
