Add /ci:add-debug-wait command for debugging CI workflows

What this PR does / why we need it:

Add /ci:add-debug-wait command for debugging CI workflows

This command automates creating PRs to add wait steps to OpenShift CI
workflows, enabling QE to debug test failures by pausing execution and
allowing SSH access to the test environment.

Key features:
- Prioritizes job config modifications over workflow modifications
- Uses OCP version to search correct job config files (e.g., release-4.21)
- Adds wait step before last test step (allowing setup steps to complete)
- Auto-commits and auto-pushes changes
- Minimal user prompts (only initial inputs + multi-file selection)
- Clear impact warnings (job config vs workflow scope)

Hi @kasturinarra. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
