Support JSON Schema 2019 and 2020

[datho7561]

Hi, this PR seemed to support for draft 04, 2019 and 2020 but was eventually revert due to issue with draft 04 (if I understand correctly). If there were no particular issues with 2019 and 2020, cant we add them back ? It seems like a lot of users would love to have support for draft 07 > features.

If it's just about adding back validators for 2019 and 2020, I dont mind creating the PR myself, but I d like to know first what was the main issue with them (if any).

We might need to use a different schema validator

Hyperjump also supports open api 3-0, 3-1 and 3-2 schemas. We can either integrate these schemas support directly in this pr or open another once this one is merged.
