Wont run with latest jsonschema installed

[jacobtomlinson]

It looks like jsonschema did a release today that has broken things here. Things here are pinned to openapi-spec-validator<0.5.0.

k8s-crd-resolver/setup.py

Line 15 in 7c23f46

'ruamel.yaml>0.17,<0.18', 'prance[osv]>=0.21.8.0', 'openapi-spec-validator<0.5.0', 'jsonpatch>=1.32,<2'

However, there is no pin on jsonschema here or in openapi-spec-validator so the latest release gets installed. I think to fix this either openapi-spec-validator needs to bump to 0.5.0 or jsonschema needs to be pinned to <4.18.
