CI: obs-crowdin-sync Python Rewrite

[Vainock]

Description

Rewrites the obs-crowdin-sync repository in Python and adds the action to this repository.

Changes that come along with it:

• Translates the UI/cmake/linux/com.obsproject.Studio.metainfo.xml.in file.
• Creates a pull request instead of pushing directly: Update Translations and AUTHORS Vainock/obs-studio#3
• Changes the name of English to English (USA) for en-US.
• Lowers the requirements for new languages to be added to the UI/data/locale.ini.
• Host the Language string in a separate Language Name file on Crowdin, remove it here.

Makes the organization/repository secret CROWDIN_SYNC_GITHUB_PAT obsolete.

Motivation and Context

The obs-crowdin-sync repository was too much for what it solves.

This solution is better for integration testing, easier to extend, easier for error analysis in the log because you don't have a huge bundled script and much cleaner to look at.

Pushing directly to the repo is bad, creating a PR is safer and transparent.

How Has This Been Tested?

Locally and Vainock#3. The update-crowdin-locales action was tested in a obs-studio and obs-browser fork.

Blocked by #10658, once merged please update your code to only translate UI/cmake/linux/com.obsproject.Studio.metainfo.xml.in and not UI/xdg-data/com.obsproject.Studio.metainfo.xml.in.

The latter is in the deprecated CMake path, the former is the new one.

@tytan652 Should it also update UI/cmake/linux/com.obsproject.Studio.desktop instead of UI/xdg-data/com.obsproject.Studio.desktop?

[tytan652]

Yes

I think the change about going away from xdg-data folder has completely gone unseen. We found out about it recently through metainfo regression in CI.

Ready for review.
