fix: support for repairing malformed array schemas

[erunion]

🧰 What's being changed?

This updates our @readme/oas-tooling and @readme/react-jsonschema-form dependencies to resolve a couple issues with malformed array schemas:

• If an array schema did not have an items property, we would fail to render the operation.
• If an array schema had an items property that evaluated to {}, we would fail to render the operation.

What will happen now is if we encounter one of these malformed schemas where items is missing, we'll repair it and add items: {} so that the array can be utilized as a standard mixed-data input.

See readmeio/oas#138 and readmeio/react-jsonschema-form#11 for the respective fixes in @readme/oas-tooling and @readme/react-jsonschema-form.

🧪 Testing

Check the updates to types.json for the example cases.
