feat: change minor pattern to support optional conventional commit scopes

The Conventional Commits spec allows optional scopes to be present after the change type, e.g. `feat(scope):`. The current minor pattern will only bump the minor version number if the pattern exactly matches `feat:`. This change is backwards compatible and adds support for these scopes.
