Merge Tor and Tails Weblates
Ref: [TPA-RFC-73: Tails infra merge roadmap - Weblate](https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-73-tails-infra-merge-roadmap#weblate)
This is currently mapped to happen in 2028, but I'm creating this issue as a placeholder so we can start coming up with a plan.
- [ ] Decide between self-hosted or not and come up with a plan
- [ ] Determine who are the service admins that should keep an eye on monitoring (eg. failures in the integration script)
- [ ] Migrate the "Translation Platform Team" secrets away from keyringer
- [ ] Forward the contact address (currently weblate@tails.net, but [may change](https://gitlab.torproject.org/tpo/tpa/wiki-replica/-/merge_requests/63#note_3149394) in the future) to Weblate admins
- [ ] Update documentation: https://tails.net/contribute/how/translate/
