This function is a wrapper for nox.sessions.Session.install. It
invokes pip to install packages inside of the session's virtualenv.
Additionally, pip is passed a constraints file generated from
Poetry's lock file, to ensure that the packages are pinned to the
versions specified in poetry.lock. This allows you to manage the
packages as Poetry development dependencies.
