chore: migrate Openshift bundles to FBC

[vrutkovs]

Cleanup release scripts and manifests, move most of the logic into Makefile.

See https://redhat-openshift-ecosystem.github.io/operator-pipelines/users/fbc_onboarding/ for FBC details.

Fixes #2037

TODO:

• Find a way to test this safely
  Generated 0.68.4 bundle using this Makefile and its identical to the generated catalog bundle
• Support channels - beta / latest / lts?
  Now defined in the file
