Add translations teams

[scottrigby]

To get #148 ready to commit, I'm removing the sketch I made for documenting the translation teams – because these teams don't exist yet as GitHub teams on the open-gitops GitHub org. This issue is to remind us to do that.

| translations | active | ADD | ADD |
| translations/LANGUAGE | ADD | ADD | ADD |

• [ ] Add translations/LANGUAGE GitHub team, per language
• [ ] Invite folks who helped with each language translation to their respective team (they can choose to accept the invite to that team if they wish)
• [ ] Publicly document those teams and team members (currently in this PR #148)
