Issue Description

After working on #1326 it was discovered that the current release process for the devfile registry operator is presenting issues when trying to automate the tasks required to cut a release. Currently we are using release branches that represent a major version, such as release-v0, release-v1. This presents issues when we are trying to cut a new minor or patch release to the respective major where the base is coming from main. The automation runs into issues because of differing git histories between the release branch and main, resulting in manual merge resolution which defeats the purpose of automating the process. In order to prevent this from happening we need to adjust the release process to better fit our needs.

Acceptance Criteria

• Update Release Process Documentation for Registry Operator #1516
• Alter Current Registry Operator Release Branch Name #1517
• Update registry operator automation issue to reflect new requirements
  • Changes will have to be made to the PR that is currently marked as a draft
  • Devfile registry operator release automation  #1326
