[Python][CI] Missing scientific nightly builds

[drammock]

Describe the bug, including details regarding any error messages, version, and platform.

Some nightly builds being uploaded to https://anaconda.org/scientific-python-nightly-wheels/pyarrow/files seem to be missing. Specifically the one missing that is causing CI failure for MNE-Python is a cp312-manylinux-x86_64 build... but if I'm scanning the list correctly, all the manylinux builds are aarch64 now, there are no x86_64 linux builds for any Python version.

Component(s)

Packaging, Python

xref to #40216 (where addition to the Scientific Python nightlies index was discussed) in case that's helpful

This should work now:
https://anaconda.org/scientific-python-nightly-wheels/pyarrow/19.0.0.dev240/download/pyarrow-19.0.0.dev240-cp312-cp312-manylinux_2_17_x86_64.manylinux2014_x86_64.whl

There was an issue for some days where x86_64 nightly wheels were failing to be uploaded and they might have been deleted from the index due to several days failing in a row.
If you can confirm we can close the issue.

Thank you!

Looks like as of today the windows builds are now missing (pretty sure they were there in our CI runs yesterday):

https://anaconda.org/scientific-python-nightly-wheels/pyarrow/files

Was this intentional / expected or no?

The windows job worked and seems to upload fine: https://github.com/ursacomputing/crossbow/actions/runs/12706005316/job/35418101771#step:22:121

We are only pushing wheels and not cleaning them up afaik, so not sure why they don't show up.
Edit: actually the path seems to be messed up https://github.com/ursacomputing/crossbow/actions/runs/12706005316/job/35418101771#step:22:3

During the PR i triggered an upload of the windows wheels so they are available again. With the next nightlybuild everything will line up again 👍
