http2=True,

We recently discovered httpx does not perform well without passing in an ssl context (home-assistant/core#89932)

see encode/httpx#2609 encode/httpx#838 (comment)

The shared helper will be updated for this issue as well so it can be used and passed the library

from homeassistant.helpers.httpx_client import get_async_client to get the shared client

from homeassistant.helpers.httpx_client import create_async_httpx_client to create a new one (if you need to recreate or need you own)
