Support zod's infer type

When using a Zod validator and then passing it to TSOA, it throws this error: Error: No matching model found for referenced type infer.

Types File

export const MyValidator = z.object({
  result: z.object({
    price: z.string().nonempty()
  }),
  code: z.number(),
  msg: z.string().nonempty()
})
export type MyResponse = z.infer<typeof MyValidator>

Then use it in TSO

 @Get()
  public async getRequest (): Promise<MyResponse> {

Expected Behavior

When running yarn tsoa spec-and-routes I expect TSOA to be able to use the inferred type generated by Zod.

Current Behavior

It crashes with

Generate routes error.
 Error: No matching model found for referenced type infer.

I’ve labeled this to avoid the bot. Please vote instead of commenting, and feel free to open a PR to fix this.

I assume because ReturnType is a type reference to a type that we already try to resolve via the mechanism I described.
