Zod `preprocess` works but `coerce` and `tranform` do not work with trpc-openapi

[ax-at]

When Zod's coerce and transform are used to modify the output schema, the generated OpenAPI document does not reflect those modifications. However, the API output reflects these modifications. Also, the TypeScript compiler shows errors about not being able to match between the .output() zod validation and the return type from the .query() method.
