CLI: Bump the 'jsonschema' version (#16635)

* CLI: Bump the 'jsonschema' version

Update the used meta-schema from Draft 7 from 2018 to the latest one,
Draft 2020-12.
Currently, the validator falls back to Draft 7 if the newer validator is
not available. Draft 2020-12 support was introduced to 'jsonschema' in
version 4.0.0.

* Fix formatting
