Fix poetry locks missing hashes. (Cherry-pick of pantsbuild#16112)

This was due to this change on PyPI:
  https://discuss.python.org/t/backwards-incompatible-change-to-pypi-json-api/17154

Which was fixed in Poetry yesterday here:
  python-poetry/poetry#5973

Unfortunately, the full fix requires blowing away the non-Pants
controlled Poetry cache at `~/.cache/pypoetry` on Linux and
`~/Library/Caches/pypoetry` on Mac.

Fixes pantsbuild#16111

(cherry picked from commit b97936e)
