ci: correctly point PyPI publishing to the ops-scenario packages

[tonyandrewmeyer]

working-directory is specifically for run steps. For the gh-action-pypi-publish action, with: packages-dir should be used.

I'm not sure how to test this pre-merge (to avoid it being wrong again, although I've gone through the documentation more carefully this time). I can't run the action against this branch, and I can't run the action in my fork (because the trusted publishing system requires it to be from the real repo). Suggestions welcome!

I guess the best way to test will be to run the test pypi job manually after merging this

re testing: push to test pypi from a branch with made up package version.

Edit: I guess that requires setting secrets for the branch and possibly tweaking the test.pypi trusted publishing temprarily?

[tonyandrewmeyer]

Tested and [works fine] 🎉 - I'm reasonably confident that this means that publishing to actual PyPI will also be fine.
