Update to latest poetry-plugin-export to fix urllib3 multiple versions issue and unpin urllib3 (#10169)

We can use modern urllib3 now! They
[fixed](https://github.com/python-poetry/poetry-plugin-export/pull/286)
the poetry
[issue](https://github.com/python-poetry/poetry-plugin-export/issues/183)
and shipped it!

Since this PR updates the requirements file, it pulls in the new
`josepy` release, so I've silenced those warnings here. If I should do
that in a separate PR lmk.
