📝 (label-actions.yml): add GitHub Actions workflow for issue labeling (…

…#2263)

Introduce a new GitHub Actions workflow to automate issue management.
This workflow automatically handles issues labeled as
`needs-discussion`, `needs-code-formatting`, and `retry-latest-version`.

- `needs-discussion`: Unlabels `bug` and `triage`, comments to create a
discussion, closes, and locks the issue.
- `needs-code-formatting`: Comments to format code or logs for better
readability.
- `retry-latest-version`: Comments to try the latest version of the
tool.

This automation helps maintain a cleaner and more organized issue
tracker by guiding users to follow best practices and ensuring issues
are relevant and up-to-date.
