When building scheduled wheels, run count-dists as a successful no-op

[radarhere]

Alternative to #9248

Normally, our scheduled Wheels jobs update wheels to scientific-python-nightly-wheels - https://github.com/python-pillow/Pillow/actions/runs/18331606908

Our most recent scheduled Wheels jobs did not - https://github.com/python-pillow/Pillow/actions/runs/18437781793

This is because #9239 made 'scientific-python-nightly-wheels-publish' require 'count-dists', which requires 'sdist', but 'sdist' does not run when scheduled.

This PR suggests always running 'sdist', but if the jobs are scheduled, skip all the steps within it.

Why does 'sdist' does not run when scheduled? To only upload wheels to scientific-python-nightly-wheels and avoid a ~50 MB zip?

Or perhaps unhook the 'count-dists' check from the scientific-python-nightly-wheels flow?

It turns out I suggested it a year ago. I expect I just thought it wasn't necessary to upload it. If you'd like to though, I have no objection. I've created #9248

All other things being equal, I think it would be better to know if we suddenly start uploading extra wheels to scientific-python-nightly-wheels.

I checked a few others at https://anaconda.org/scientific-python-nightly-wheels/ and didn't see any sdist, so probably better not to upload a fairly large file. And the clue's in the (scientific-python-nightly-wheels) name.

Agreed.

How about we use #9248 and do something like rm pillow*.tar.gz in the scientific-python-nightly-wheels-publish job just before upload?

Sure. I've updated the PR, just changing the 'pattern' used for matching in scientific-python-nightly-wheels-publish.

Closed in favour of #9248.
