bump version of selene to 2.0.0rc4, pin selenium <4.10

pytest-selenium requires selenium <4.10

bumping version of selene because there are package dependency
resolution errors when we try to use 2.0.0rc2.

in Makefile's `pyenv` target, try to delete the virtualenv before
creating it. that way, we can get a clean virtual environment.
