Incompatible with jsonschema 4.10.0

They have created their own evolve method instead of using the attrs.evolve and that breaks a lot.

I have also created an issue on their end: python-jsonschema/jsonschema#982

OAS31 will be fixed but for OAS30 check the issue #48

[Wim-De-Clercq]

I believe since 4.10.2 it works again even for OAS30, due to changes on jsonschema's end (python-jsonschema/jsonschema@a8c3b14).
But, as you said, it is still a technically unsupported thing.

thanks for your work on this
