[Crowdin] Improve the process of updating translations

[veloce]

We cannot anymore update translation with ./script/update-arb-from-crowdin.mjs.

To be future proof we should:

• leverage crowdin API
• automate more the process

The script now only download the translations, it does not build them. A better solution would be a GitHub action than can be triggered manually and that would:

• build the project using crowdin API
• download the project (via API) and update ARB file (what is doing the script right now)
• run flutter gen-l10n to update the dart files
• create a PR with the updated translations so we can review the changes

The more obvious course of action seems to be to use Weblate. Lichess prides itself on being open and no spying.

The translations I see now are awful.

That's probably a discussion that should be raised over at https://github.com/lichess-org/lila, since the app reuses a lot of the existing Lila's crowdin translations, so it's not really feasible to switch the backend just for the app.
