Include translations in builds (#4089)

* Pull/push strings via Git instead of via API

This is necessary because the Weblate API doesn't handle stale strings
well. In particular, it won't remove them automatically.

* Schedule workflow instead of running on every commit

This is so we can minimize downtime for Weblate translations.

* Prevent pull requests modifying translations

* Don't commit translations during the merge freeze

* Add release notes

* Undo rename

* Don't commit translations nightly, per feedback

* Include translations just-in-time in builds

* Revert "Prevent pull requests modifying translations"

This reverts commit 8c19a0ce13.

* Re-ignore translations

* Update release notes to be accurate

* Create missing directory

* Fix conditional logic
