[MLGO][Infra] Add mlgo-utils to bump-version script (#100186)

This patch adds support in the bump-version script for bumping the
version of the mlgo-utils package. This should hopefully streamline the
processor for that with the rest of the project and prevent having to
manually update this package individually.
