Cleanup Request method parameter.

[tomchristie]

The Request() class currently has a method parameter that's out of sync with client.request(...) and httpx.request(...). This is nominally an API change, tho I think it's actually a bugfix in practice.

Oh, it seems this change was breaking and affected the compatibility of another library with httpx. It looks like we should take changes that require a major release a bit more seriously.

This kind of change breaks specific versions of other projects, without giving them any chance to avoid it :c

Thanks @karpetrosyan, good to see type checker checking types.

Hishel is looking really smart. Most obvious action points...

• Reintroduce a clear "pinning" note on the httpx README and homepage. This might either recommend ==0.28 or <1.0.
• Do whatever we can this side communications-wise to help ensure our dependencies are neatly pinned.
• Ensure future updates have a clear transition approach. (pre-releases might be appropriate.)
