shouldRetry function does not execute on 200 responses

[joeynenni]

For GraphQL APIs 200 status codes are used even when there are errors. In order to retry when there are errors in a 200 response the shouldRetry function should execute.

The betterFetch function returns before the error handling code can execute: https://github.com/Bekacru/better-fetch/blob/main/packages/better-fetch/src/fetch.ts#L152
