fix(ci): add checkout step to auto-approve-bot-prs workflow (redhat-developer#3717)

* fix(auto-approve): add checkout step to fix 'not a git repository' error

The gh CLI commands were failing because the repository wasn't checked out.
Added actions/checkout@v4 step to ensure git context is available.

* test: temporarily enable workflow for polasudo to test functionality

* test: add fix/auto-approve-bot to eligible patterns for testing

* fix(auto-approve): add issues:write permission for label management

* fix(auto-approve): use pull_request_target for proper permissions

Using pull_request_target instead of pull_request allows the workflow
to run with write permissions even for PRs from forks or bot accounts.
This is necessary for adding labels and approving PRs.

* Fix auto-approve workflow: use REST API for adding labels instead of gh CLI

* test: trigger workflow re-run

* test: remove trigger file

* test: temporarily disable user condition to test workflow

* fix(auto-approve): use pull_request_target and add issues:write permission

- Change trigger from pull_request to pull_request_target for proper permissions
- Add issues:write permission required for label management
- Add --repo flag to gh commands for explicit repository context
- Remove checkout step (not needed with pull_request_target)
- Fixes GraphQL: Resource not accessible by integration error

* fix(auto-approve): add fix/auto-approve-bot pattern for testing

* feat(auto-approve): add push trigger for faster testing feedback

- Add push trigger on fix/auto-approve-bot branch for immediate testing
- Handle both push and pull_request_target events in workflow logic
- Add logging step for push events to show eligibility check results
- Only run label/approve actions on actual PR events

* test: trigger workflow rerun

* test: simplify push logging to debug workflow triggering

* test: add temporary PR labeling simulation for fork testing

* test: enable real PR labeling on push events for testing

* test: target PR #1 in fork for labeling test

* test: target PR #2 for labeling demonstration

* feat: clean up auto-approve workflow for production use

- Remove all testing code (push triggers, test PR numbers, debug logging)
- Simplify workflow to only run on pull_request_target events
- Only run for rhdh-bot PRs
- Keep fix/auto-approve-bot pattern for final testing before merge
- Ready for production deployment

* test: temporarily allow polasudo for final workflow testing

* feat: finalize auto-approve workflow for production

- Remove temporary polasudo testing allowance
- Remove fix/auto-approve-bot test pattern
