AsyncHttpClient getContent does not support a timeout

[FedericoCeratto]

Description

From the documentation: "Currently only the synchronous functions support a timeout". https://nim-lang.org/docs/httpclient.html#timeouts

Any transient network failure or loss of connectivity can leave futures pending forever, making AsyncHttpClient not suitable for long-lived processes.

Nim Version

1.6.10

It doesn't support a timeout because it's async, and you can just use withTimeout from asyncfutures

So, I guess the issue right now is mainly about explicitly documenting withTimeout in the "Timeouts" section for httpclient?
