OpenAPI 3.1

[neb42]

We're currently using OpenAPI 3.0.

3.1 adds in arrays of types. This is useful as a component config item may want to accept multiple types, eg. the Text component could accept anything and convert it to a string. We should also aim to stay up-to-date with OpenAPI.

This needs some thinking as to how we will handle it both coming from the API, in the component definitions, and in the builder client.

• If an API returns ['string', 'number'] and the component expects 'string' is that valid?
• If an API returns 'string' and the component expects ['string', 'number'] is that valid?
• If a component config item has multiple types in a static mode, what do we render? Is there a priority list? array/object, string, number, boolean?
• If a component config item has multiple types including array or object should we still support form mode?
