typescript-react-query error handling

### Describe the bug

The error field only contains 'message' of the first error instead the whole error array, extensions are also missing.

The error field should contain something like this:

`export type GraphQLError = { message: string, extensions?: GraphQLErrorExtensions }
export type GraphQLErrorExtensions = { path?: string, code?: string }`

### Steps to Reproduce the Bug or Issue

This part in the fetcher should get fixed:

` const json = await res.json();

if (json.errors) {
const { message } = json.errors[0];

throw new Error(message);
}`

### Expected behavior

Graphql standard errors array should be set.

### Screenshots or Videos

### Platform

Docker

### Codegen Config File

_No response_

### Additional context

_No response_

Start by locating the fetcher code shown in the issue and read how the JSON response's errors field is parsed. Verify the GraphQL error response shape and update the behavior so the complete errors array, including extensions, is preserved; the issue does not name a test, so confirm the result against the reproduction and expected behavior described here.
