Currently, rules_pyvenv installs all the python deps by symlinking them in site-packages. However, in bazel, the python deps are actually added to the PYTHONPATH, which means that for some deps, just symlinking into site-packages doesn't work.

However, venv supports this via pth files. Would it be feasible to add a flag to py_venv to also create a .pth file to append these deps to the PYTHONPATH as well?

directories specified in the pth file to the PYTHONPATH, which exhibits
the behavior we want.
