validation schema for overlay documents is not referenced by the spec

[karenetheridge]

The specification document does not mention the existence of the JSON Schema document used for overlays.

It is here: https://spec.openapis.org/overlay/1.1/schema/2026-01-14 -- and the index of all schemas is https://spec.openapis.org/overlay.

Hi @karenetheridge
From the TDC call today: This is already linked here today

Would you mind sending a PR to reference it in the readme as a stopgap please?

We might as well add a similar wording than the OpenAPI specification in the next release. We might as well consider patches.
