Most recent JSON Schema version is not supported

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

As I understand it - The $schema keyword is used to point to a JSON Schema that describes the shape of a valid JSON schema itself.

The most recent version of the JSON Schema spec is 2020-12 https://json-schema.org/specification.html

If we try use a schema with

  "$schema": "https://json-schema.org/draft/2020-12/schema",

RSJF will show a validation error:

no schema with key or ref "https://json-schema.org/draft/2020-12/schema"

Expected Behavior

The most recent version of JSON schema should be supported.

Steps To Reproduce

1. Navigate to: https://rjsf-team.github.io/react-jsonschema-form/
2. Paste "$schema": "https://json-schema.org/draft/2020-12/schema", into the top level of the schema
3. Submit the form
4. Observe the validation error
