[SecuritySolution] OpenAPI generator generates invalid TS source code depending on components schemas order

[machadoum]

The order in which the components are declared might cause TS errors when we use $ref.

Current behavior:

The following yaml:

openapi: 3.0.0
info:
  title: Test components schema Order
  version: '2023-10-31'
paths: {}
components:
  schemas:
    IdOrUndefined:
      $ref: '#/components/schemas/Id'
      nullable: true
    Id:
      type: string

Generates the following code:

export type IdOrUndefined = z.infer<typeof IdOrUndefined>;
export const IdOrUndefined = Id.nullable();

export type Id = z.infer<typeof Id>;
export const Id = z.string();

Which contains the following error:

Block-scoped variable 'Id' used before its declaration.ts(2448)
myTest.gen.ts(23, 14): 'Id' is declared here.
Variable 'Id' is used before being assigned.ts(2454)
const Id: z.ZodString

Expected behavior: It should generate valid TS code for any order in which components are declared.
