- remove ubuntu 21.04 from CI (end of life)
- adjust matrix strategy for clang.yml
- Use lessons learned from RetroArcher on localize.yml, crowdin.yml, and locale.py
- Add end of life comments to Dockerfiles
- Adjust dependency order in Dockerfiles
- Rename extracted template file to `sunshine.po`
- Add `crowdin.yml`
- Remove `--init` and `--update` from `localize.yml`
- Crowdin will initialize new languages and update existing ones
- Only run when changes are made on files inside 'sunshine' directory
- Prevents workflow from running again when this workflow pushes changes back into 'locale' directory
- Should be cleaner than using 'paths-ignore'
- Don't run if commits are all in 'locale' directory
- Allows pushing changes back into nightly from this workflow without triggering and endless loop
- Don't run job unless event is 'pull_request.merged'
