chore(build): sw-1647 workflow mod, prep for branch rename

[cdcabrera]

What's included

• chore(build): workflow mod, prep for branch rename

Notes

• Prep work for moving to using main and stable branches where...
  • main is a representation of beta/preview staging
  • stable is a representation of stable staging, and related Git hashes are used to do production releases
• Aligns documentation to the branching structure
• Aligns GitHub action workflows to the branching structure
• Aligns Travis temporarily to the new branch structure while behind the scenes routing shifts to the container build
• This will deactivate ROSA in the OpenShift group variant select/dropdown across all environments @diegomaranhao . ROSA will still be directly available at [subscriptions ui]/rosa
• AFTER this PR is merged...
  • We'll confirm that Travis is still functioning and pushed related code towards stage-preview, then
  • A new stable branch will be created, then
  • We'll confirm that Travis is still functioning and pushed related code towards stage-stable
  • If any failures happen at the Travis level we'll merge subsequent mods
  • The dev branch will be dated/renamed, then retired
