chore: add localization reminder workflow

[netbe]

Issue

Adds a GitHub Actions workflow that comments on a PR when new localization strings are introduced. The comment lists each new key with its English value and reminds contributors to ensure German translations are completed after merging to develop.

The workflow triggers on changes to en.lproj/*.strings and *.xcstrings files. It detects only genuinely added keys (not edits or deletions), and updates the comment in place on each push so the list stays accurate.

Testing

1. Open a PR that adds a new key to an en.lproj/*.strings file — verify a comment appears listing the key and its English value.
2. Open a PR that adds a new key to an .xcstrings file — verify the comment shows the correct English value fetched via jq.
3. Push a follow-up commit adding more strings — verify the comment is updated rather than duplicated.
4. Open a PR with no localization changes — verify no comment is posted.
