doc: warn against concurrent http2stream.respondWithFD by addaleax · Pull Request #18762 · nodejs/node

@addaleax 

Upcoming changes to move away from synchronous I/O on the main
thread will imply that using the same file descriptor to
respond on multiple HTTP/2 streams at the same time is invalid,
because at least on Windows `uv_fs_read()` is race-y.

Therefore, warn against such usage.
