Install pylint-sarif-unofficial via pipx

And use the new version.

This change--both installing it with pipx on CI instead of having
it as a development dependency, and using the new version--is to
work around EliahKagan/pylint-sarif#19.

This also upgrades (other) direct and indirect dependencies.
