Dequarantines and removes from smoke

What does this MR do?

Dequarantines create_and_process_pipeline_spec.rb and removes it from the smoke test suite. After investigation, it looks like there isn't anything wrong with the test itself. The issue was around runner. 9 months ago, when it was quarantined, there was an increased occurrence of this test failing with:

Verify Pipeline creation and processing users creates a pipeline which gets processed
     Failure/Error: expect(show).to have_status(status), "Expected job status to be #{status} but got #{show.status_badge} instead."
     
     QA::Support::Repeater::WaitExceededError:
       Wait failed after 30 seconds

Since being quarantined, this specific failure hasn't been coming up as frequently. I want to dequarantine this and remove it from the smoke test suite to allow this spec to run more without being a hard block on deploys and get a better idea too how frequently it is still hitting this error. If it becomes too noisy, I'm going to propose a follow up MR to add :skip tag to it until the runner issue can be resolved.

Check-list

• General code guidelines check-list
  • Code review guidelines
  • Style guides
• Quarantine test check-list
  • Follow the Quarantining Tests guide.
  • Confirm the test has a quarantine: tag with the specified quarantine type.
  • Note if the test should be quarantined for a specific environment.
  • (Optionally) In case of an emergency (e.g. blocked deployments), consider adding labels to pick into auto-deploy (Pick into auto-deploy priority1 severity1).
• Dequarantine test check-list
  • Follow the Dequarantining Tests guide.
  • Confirm the test consistently passes on the target GitLab environment(s).
• To ensure a faster turnaround, ask in the #quality_maintainers Slack channel for someone to review and merge the merge request, rather than assigning it directly.
