Support docker 7.x

[jonathangreen]

Docker 7.1.0 contains a fix necessary to use the latest version of requests. tox-docker not supporting docker 7.x is keeping my project from being able to update. Would it be possible to support docker 7.x in tox-docker?

Thanks for posting this! I was coming to do the same.

The full/longer description of the issue started here: docker/docker-py#3256.

From what I can tell, those of us using tox-docker can't benefit from the docker fix until tox-docker supports Docker 7.x.

I put up a small PR to resolve this one here: #182

OK, I've just published https://pypi.org/project/tox-docker/5.0.0/ with this fix.

5.0 removes support for tox 3, and has a breaking change if you were using ports in your tox.ini. Check the README for details on how to use the replacement.

Many thanks @jonathangreen for the contribution!
