Use PR for openstack-k8s-operators-ci workflow updates

Change the 'Update openstack-k8s-operators-ci workflows' step to create
a pull request instead of directly committing to main branch. This follows
the same pattern as the openstack-operator update step.

Changes:
- Create a feature branch for the force-bump-branches.yaml update
- Check if changes were made before creating PR
- Create PR with descriptive title and body
- Respect DRY_RUN mode
- Use retry logic for git push operations
- Remove direct commit to main branch
