[Feature] Set custom error object in rtk-query/graphql-request-base-query

Proposal Feature: graphqlRequestBaseQuery shoud give the option to set the error response object, using the graphql response

Possible example:

export const api = createApi({
  baseQuery: graphqlRequestBaseQuery({
    client,
    customErrors: ({ name, message, request, stack, response }) => {
      return {
        name,
        stack,
        message: response?.errors[0]?.extensions?.errorMessage,
        errorCode: response?.errors[0]?.extensions?.errorCode
      };
    }
  }),
  endpoints: () => ({}),
  refetchOnMountOrArgChange: true
});

In the example the customError callback provides the error returned from the graphql-response client

My plan was to spend the day on PRs, so I’m getting to this one next 😃

Yeah, I’m very sorry - I mean I suggested you do this PR in the first place. Unfortunately I’m pretty much behind on everything right now. I’ll try to get to it soon, but it’s probably going to be end of next week.
