[Feature Flag] Rollout of pipeline_editor_empty_state_action

What

We are adding a functionality to allow user to start working on their Ci configuration even if they don't have a file or even a repository. This feature flag essentially shows/hide the CTA button that allow that functionality to be exposed.

Rollout pipeline_editor_empty_state_action feature flag and eventually remove it altogether.
