Issue Description

As a maintainer of the devfile project I want to have the release process be as efficient as possible. By automating this process it makes it simple to quickly cut new releases and reduces overall time spent by a maintainer performing the release.

Similar efforts have been implemented in devfile/api here and is planned to be implemented in devfile/registry-operator as well here. The work required by this issue would closely follow the idea implemented in the other two repositories.

Acceptance Criteria

• Create new shell script to perform automation process
• Script should perform any changes to version numbers in documentation/files (if necessary)
• Script should automate the process of pushing release (and any necessary changes) to git and tagging the commit as newest version
• Test the script on a forked repository
• Update documentation to reflect new release process/script
