[Bug]: SDK generator to support properties for allOf instructions in specs

[vscaiceanu-1a]

Package name

schematics

Package version

12.0.0

Reproduction steps

When generating an SDK for specs with properties along with the allOf instruction, the enum types are not created.

Dog:
  allOf:
    - $ref: '#/components/schemas/Pet'
  properties:
    bark:
      type: boolean
    breed:
      type: string
      enum: [Dingo, Husky, Retriever, Shepherd]

Current result

It will not generate the breed enum.

Expected result

Should generate:

export type BreedEnum = 'Dingo' | 'Husky' | 'Retriever' | 'Shepherd';

Additional comments

For now, we provide a workaround via #3013
