fix: rollback type issue

[GabDug]

34 introduced a regression, where I would get a yaml.representer.RepresenterError: ('cannot represent an object', ClientErrorEnum.CLIENT_ERROR), when generating the schema.

I rollbacked the removal of the .value: here mypy is wrong. Mypy can be corrected with djang-stubs, but installing it brings other mypy warnings.

If you want some help to improve the typing or other things, I'd be willing to help :)

I hope you'll be able to make a new release soon

Thank you for the fix and sorry for the late response.

About creating a release, I'll do so shortly after both python 3.12 and drf 3.15 are released (hopefully next week or the week after)
