In tests, handle changes in click and jsonschema (#284)

- click v8.1.4 triggers a mypy bug that causes type checking to fail.
  click is working on a fix, but until it's released, avoid that
  version.
- jsonschema 4.18.0 deprecates the older ref resolution framework.
  Until check-jsonschema can update to use the newer ref resolver,
  ignore the deprecation warnings in tests.
