Revert "[ci] automatically trigger tests in releasing PR" (#900)

Revert https://github.com/cozystack/cozystack/pull/894 due to fact this
logic does not trigger checks in pull requests

## Summary by CodeRabbit

- **Chores**
- Removed support for manually triggering the pull request release
workflow.
- Simplified release workflow to run automatically only on labeled pull
requests.
- Eliminated the step in the tags workflow that triggered release
verification via manual dispatch.
