DEVOPS-1696 - Update Version Bump workflow logic

[vgrassia]

Type of change

• [ ] Bug fix
• [ ] New feature development
• [ ] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
• [X] Build/deploy pipeline (DevOps)
• [ ] Other

Objective

This PR updates the logic in the Version Bump workflow so that it will check for the existence of a current rc branch, if necessary, before creating the PR to bump the client version. The cut_rc job has been updated to make sure the version bump PR has been merged before cutting the rc branch.

Code changes

• .github/workflows/version-bump.yml: See above.

Before you submit

• [ ] I have checked for linting errors (npm run lint) (required)

• [ ] This change requires a documentation update (notify the documentation team)
• [ ] This change has particular deployment requirements (notify the DevOps team)
