#   1. parses the version number from the branch name
#   2. updates version.py files to match that version
#   3. iterates through CHANGELOG.md files and updates any files containing
#      unreleased changes
#   4. sets the output variable 'version_updated' to determine whether
#      the github action to create a pull request should run. this allows
#      maintainers to merge changes back into the release branch without
#      triggering unnecessary pull requests
