[zod-openapi] cannot handle nested types

[matthew-kaye]

const zAddress = z
  .object({
    line1: z.string(),
    line2: z.string(),
    city: z.string(),
    province: z.string(),
    country: z.string(),
    postalCode: z.string(),
  })

const response = extendApi(
  z.object({
    data: z.object({
      ...
      address: zAddress,
    }),
  }),
);

When I try to build swagger docs based off of this I get the following error:

Found undefined and using theme.openapi options
Prerendering docs
TypeError: t.required.indexOf is not a function

It works if I make the address an empty object, but for some reason when I define the keys of the address object the required field gets messed up and becomes a boolean when it should be an array of the required fields. I've attempted multiple workarounds with no luck
