Please add support for the QUERY HTTP method

[gdubicki]

On 2025-01-07 the QUERY HTTP method, "a safe, idempotent request method that can carry request content." has reached the level of a Proposed Standard.

It solves the problem of making complex queries where the GET method is sometimes sufficient as it (according to the standard) lacks support for sending the query in the body, leaving only the query part of the URL which is limited. An often used workaround of using the POST method has a downside in that it's just the wrong method for this purpose as queries do not cause side-effects and this limits the retryabilty and cacheability of such queries.

Therefore It would be great to implement support for QUERY in Requests.

If you are open to it, I am interested in providing a PR.

As described in the template, Requests is not accepting feature requests

To be clear, QUERY is already supported. Both requests.request and requests.Session.request allow for passing an arbitrary method.
