Fix auto-promotion permissions

- Add 'contents: write' and 'actions: write' permissions to auto-promote workflow
- This should fix the 'Resource not accessible by integration' error
- Update to v2.0.3 to test the fixed auto-promotion pipeline

The auto-promotion workflow needs write permissions to merge branches
and trigger other workflows in the repository.
