Use of proxies kwarg in httpx==0.28.0

[Sergeydmitr]

Describe the bug
Cannot start bot after httpx update. httpx version 0.28.0 removes the deprecated proxies argument; this argument is hardcoded in the mattermostautodriver versions lower than 2.2.1.

How To Reproduce
Update to httpx version 0.28.0

Can we get a 2.2.1 release in pypi that addresses this?

@attzonko Addressed also in python-mattermost-autodriver - 2.3.0 as the problem stems from there.
