add selenium-axe-pyhon package to selene1x branch

pin selenium package to versions <4.10 because pytest-selenium currently
supports versions <4.10.

add py package because pytest-selenium still depends on it.

in Makefile, update `pyenv` target to try to delete the virtual environment before creating it. this way, we can get a clean virtual environment.
