Installing `tox-venv` on OSX allows `tox` tests to be run, per https://community.home-assistant.io/t/installing-hass-on-macos-osx/69292
Alternatively, `tox-venv` _could_ be added directly into the https://github.com/home-assistant/home-assistant/blob/dev/script/bootstrap file, but since nobody outside of OSX developers seem to be having this problem it seemed safer to simply note it in the documentation.
Without installing `tox-venv` the following occurs:

* Update testing info with virtual environment
Being new to python, pip and virtual environments, I tried running `tox` without activating the virtual environment. This should make it a little bit more clear for newcomers.
