Start to use the 'rules' keyword for the 'package-and-qa' job

What does this MR do?

Challenges

• 
• We need to duplicate the pattern arrays because they're YAML anchors and they aren't accessible in included Ci config (they're only accessible when using extends but we cannot use extends to reference a plain YAML array...)
• When two rules have the same if but their changes are different, be mindful of the rules order since rules are evaluated from top to bottom.

Does this MR meet the acceptance criteria?

Conformity

• Documentation (if required)
• Code review guidelines
• Merge request performance guidelines
• Style guides
• Separation of EE specific content

Availability and Testing

• CI config generates the correct jobs:

  • Without QA change: package-and-qa should be manual: https://gitlab.com/gitlab-org/gitlab/pipelines/103792716

    

  • With QA change: package-and-qa should be on_success: https://gitlab.com/gitlab-org/gitlab/pipelines/104135502
