Features
- [GH-47](https://github.com/hamdanal/rich-argparse/issues/47),
[PR-48](https://github.com/hamdanal/rich-argparse/pull/48)
The default `group_name_formatter` has changed from `str.upper` to `str.title`. This renders
better with long group names and follows the convention of popular CLI tools and programs.
Please note that if you test the output of your CLI **verbatim** and rely on the default behavior
of rich_argparse, you will have to either set the formatter explicitly or update the tests.
