Subject: [PATCH] Add version change check in the version bump workflow (#3104)

* Check if any changes to commit

* Comment out checkout since there is a git switch

* Change base branch to DEVOPS-872_version_bump_not_fail

* Remove checkout version branch since git switch does that

* Revert "Change base branch to DEVOPS-872_version_bump_not_fail"

This reverts commit 8874702469baf17598be812a0a4c44ce0cd8eeca.
