Bump jsonschema minimum version to avoid RefResolutionError

Related Issue(s):

• Closes Processing extension can't be used for validation? #845

Description:

Validating Collections with the Processing Extension led to a RefResolutionError when using jsonschema < 4.0. Since 4.0.1 was yanked from PyPi, we now pin to jsonschema>=4.0.1.

Tested with 4.0.1 and the reported error doesn't occur anymore.

There's a test-validation-error.json file at the top level of the repository -- is that intentional? IMO that file should be in tests/data-files and should be checked w/ a regression test.

Oops, sorry. I was using that to reproduce the original error. I reverted the commit that added this.
