chore: Add integration test requirement for Ansible Galaxy major version updates

- Added a new rule in the `renovate-versions-dedicated.json` Renovate preset file to
  require an integration test for Ansible-Galaxy major version updates.
- This rule is triggered when a major version update of an Ansible Galaxy dependency is detected.
- The rule adds a label to the pull request to indicate that an integration test is required.
- For non-major version updates, also includes a note in the pull request body to remind
  developers to perform a review app deployment to ensure that the upgrade works as expected.
