[bug]: Cannot specify the spec as being required

[jamescooke-xyz]

Describe the bug

If I have required properties in my spec, adding the below will validate:

apiVersion: mycrd.io/v1
kind: MyResource
metadata:
  name: example
  namespace: default
spec: {}

But adding this will not:

apiVersion: mycrd.io/v1
kind: MyResource
metadata:
  name: example
  namespace: default
spec:

We need to be able to specify that the spec is required. Either by allowing us to overriding it and explicitly setting it as [Required], or by convention (if a child property is required).

To reproduce

Any CRD created using the Transpiler won't have the spec marked as required.

Expected behavior

An ability to mark the spec marked as required.
