Add literal_enums config setting

Instead of the default Enum classes for enums, you can now generate Literal sets wherever enum appears in the OpenAPI spec by setting literal_enums: true in your config file.

literal_enums: true

Thanks to @emosenkis for PR #1114 closes #587, #725, #1076, and probably many more.
Thanks also to @eli-bl, @expobrain, @theorm, @chrisguillory, and anyone else who helped getting to this design!

Fixes

• Typo in docstring (fix: Typo in docstring #1128)

Use literal value instead of HTTPStatus enum when checking response statuses

Python 3.13 renamed some of the HTTPStatus enum members, which means clients generated with Python 3.13 may not work
with older versions of Python. This change stops using the HTTPStatus enum directly when checking response statuses.

Statuses will still be checked for validity at generation time, and transformed into HTTPStatus after being checked
at runtime.

This may cause some linters to complain.
