`request()` retries fetch twice, which can cause timeouts that are twice as long as requested

`request()` tries twice to get a socket, connect, and fetch twice:

This is confusing because if it tries a second time, it can make the default or user specified timeout (see #9210) appear to take twice as long as requested.

I am not sure about the circumstances the comment is talking about:
https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/12e6b47db7b905d2291f3f235160fcf95f7d0769/adafruit_requests.py#L513
and whether it's true for non-ESP32-SPI, etc. I wonder if some checking or resetting of the socket can be done in advance.
