fix(uipath-platform): retry 500 responses for GET requests

GET is idempotent, so a bare 500 can be safely retried when the request is a GET, even though it's left non-retryable for other methods since it may indicate a non-idempotent, non-transient server bug. Co-Authored-By: Claude Sonnet 5 <[email protected]>
