feat: add QUERY HTTP method support per RFC 10008

[ajaymahadeven]

Adds HttpMethod.QUERY to the HttpMethod enum so Azure Functions HTTP triggers can declare and handle the new QUERY method (RFC 10008), which provides a safe, read-only alternative to POST for requests requiring a body.

Hi @hallvictoria , it looks like I missed updating the ASGI/WSGI test assertions when adding the QUERY method.

I've pushed a fix in the latest commit — the hardcoded methods list in _test_http_external_app now includes QUERY. All 765 tests pass locally. Could you re-trigger CI with /azp run? Please and thank you.

Hi @hallvictoria, apologies for that — fixed in the latest commit. All 767 tests pass locally including flake8.
