Activate examples profile during release preparation

[michalvavrik]

Summary

I dropped this yesterday https://github.com/quarkus-qe/quarkus-test-framework/pull/1431/files because AFAICT there is no reason to prepare examples. However release fails https://github.com/quarkus-qe/quarkus-test-framework/actions/runs/12291828284/job/34309866608 and this change is one of few ideas I have for why it fails.

Please check the relevant options

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Dependency update
• Refactoring
• Release (follows conventions described in the RELEASE.md)
• Breaking change (fix or feature that would cause existing functionality to change)
• This change requires a documentation update
• This change requires execution against OCP (use run tests phrase in comment)
