gh-135615: Rephrase HTTP status codes overview

[sharktide]

The HTTP module supports status codes that are unregistered/unofficial. Take http status code 418: I'm a teapot Due to the save418 movement (https://save418.com/), python decided to preserve http code 418 in its codebase, but the documentation contradicts itself.

In the documentation, right above the table of status codes supported by the http library we have this:

Supported, IANA-registered status codes available in http.HTTPStatus are:

This is factually incorrect, because code 418, (among others) is not official, and this PR lists 418 as an exception

Fix #135615

• Issue: HTTP modules documentation displays a list of both unsupported http and supported codes, contrary to caption. #135615

Better to note that 418 is an exception than to remove this useful reference.

Thank you for the reminder.

Revisiting the substance of this change, I'm on the fence. The website lists 418 as "418 (Unused) [RFC9110, Section 15.5.19]". This contrasts to other ranges, which are listed as "Unassigned". The RFC goes on to note that "the 418 status code is reserved in the IANA HTTP Status Code Registry".

If we do go ahead with this change, I've suggested a rewording that I hope clarifies matters.
