add --force flag to ln

[technillogue]

The pip install stage by default brings pip's dependencies: distutils, setuptools, wheel. Pyenv also brings these packages, so trying to symlink the ones from pip causes an error

Actually now that I look at it ln makes all of the symlinks it can even if some of them already exist, so a || true would also take care of this instead of --force

Happy to go with --force as a first pass, and pivot to || true if that proves problematic.
