OpenAPI 3.1.x schemas falsely fail validation with ajv

[mnahkies]

Expected Behavior
A valid openapi: "3.1.0" document should pass initial validation against the openapi 3.1 specification without errors.

Actual Behavior
Validation fails with confusing / obtuse error messages.

Cause
It seems that ajv does not support some of the keywords used in defining the specification properly, causing it to fail:

• OpenAPI 3.1 examples not validating through AJV using OpenAPI 3.1 spec OAI/OpenAPI-Specification#2689
• Support $dynamicAnchor and $recursiveAnchor in any schema location (not only root) ajv-validator/ajv#1745

The best thing to do is probably wait for ajv to improve support for $dynamicAnchor, and skip validation for 3.1 specifications in the meantime.
