Build bundle on MR and default branch pipelines

What does this MR do?

Build bundle on MR and default branch pipelines

• Build bundle and catalog image on on default branch and MR pipelines.
• The images are pushed to a staging repository, while release/tag pipelines keep pushing to the non-staging repository
• Removed Go cache setup which is not needed for bundle building

This helps us to validate that our CI Podman setup and bundle building is working outside of the release pipelines.
