Use tox 4 for release testing

[oerc0122]

Not backwards compatible with prior releases, requires #324 release.

Cannot test without #324 release.

I wonder if this ultimately needs to be the PR that breaks release testing into separate PyPI and Conda tests: tox and conda don't play together very nicely without the tox-conda package which is not compatible with tox 4. Specifically, our tox setup needs access to interpreters for multiple python versions, and conda only wants to give you one of those at a time. We may need to switch conda environments at the workflow level to test those builds.

This is looking good, only Conda tests are failing now.

These are mostly due to me I suspect, but rather than interfere with your work on the branch

[oerc0122]

Have you given this tox a test with a manual run or workflow trigger?

Have just run it and looks good: https://github.com/pace-neutrons/Euphonic/actions/runs/12356249062

I would like to split the PyPI and Conda tests next so that something goes green when PyPI is good 😆 .

I don't think it matters much if that is done before or after #332 is merged.

Splitting it into two steps in the workflow with tox -e ENV should be easy.

Separate workflow is better because these are different releases, typically built and tested on different days. It may even be best not to use tox for the conda one.
