Objects with properties of type object that uses readonly are required

[torleifhalseth]

What are the steps to reproduce this issue?

1. Create a schema with an object type that has a property that is an object or array of objects that has read-only properties. Example:

 PatchedEnrollment:
      type: object
      properties:
        created:
          type: string
          format: date-time
          readOnly: true
        enrolled_user:
          $ref: "#/components/schemas/EnrollmentUser"

What happens?

The NonReadonly is added to the PatchedEnrollment type in the generated hooks, but the read-only properties defined on EnrollmentUser are still required.

What were you expecting to happen?

I was expecting/hoping all the read-only properties would be ignored.
