Issue: `pip freeze` creates links to local files in tmp directories, which are later inaccessible to recreate a venv. Fix: Use `pip list --format=freeze` instead (see https://stackoverflow.com/questions/62885911/pip-freeze-creates-some-weird-path-instead-of-the-package-version)

Updating the commands in this page accordingly. At such time that pip freeze works, this can be reverted.
