pysr/test/incremental_install_simulator.dockerfile

# This dockerfile simulates a user installation that first
# builds PySR for Python 3.9, and then upgrades to Python 3.10.
# Normally this would cause an error when installing PyCall, so we want to
# ensure that PySR can automatically patch things.
