Update h2 pin?

[HarrySky]

Hi, some time ago h2 pin was updated in httpcore: encode/httpcore#208

But it is still pinned to 3.* in this package's http2 extra:

httpx/setup.py

Line 65 in 0f280af

"http2": "h2==3.*",

This is not an issue, as I can just add h2>=3,<5 to my setup.py instead of using httpx[http2], but maybe you want dependencies to be in sync with httpcore.

EDIT: Using git blame we can see that before http2 extra - httpcore[http2] was used instead of h2 dependency directly.

Thanks, that's interesting.

It seems the direct fix would be to bump h2 in HTTPX as well (we don't have dependabot here so dependencies don't get bumped automatically).

I wonder what would happen if we had the http2 extra refer to httpcore[http2], though?
