ci: Update browser installation methods

This commit updates the method for installing a headless browser for use
with selenium. Previously, it was installed globally using the
'seleniumbase' tool. This commit updates to first install 'seleniumbase'
into a venv, and then install browsers globally. This prevents
dependency conflicts.
