fix: update wiki-sync workflow to use PR instead of direct push (#26)

Repository rules require all changes to go through pull requests
and have verified signatures. Modified wiki-sync workflow to:

- Use peter-evans/create-pull-request action
- Create automated PR for wiki changes
- Respect branch protection rules
- Add proper labels (documentation, automated)

This fixes the 'push declined due to repository rule violations' error.
