Fix Nightly PyPi Artifact Wheels Build

[geruh]

Rationale for this change

Nightly build has been failing for some time since dropping support python 3.9 support. That PR included a change that dropped the upper bound of the python version.

-        CIBW_PROJECT_REQUIRES_PYTHON: ">=3.9,<3.13"
+        CIBW_PROJECT_REQUIRES_PYTHON: ">=3.10"

That made cibuildwheel try Python 3.14 and sometimes the free-threaded *t builds. Those are part of the PEP 703 effort to allow Python without the GIL. Therefore, the avro related code would throw a message breaking the build and I don't think this has been evaluated yet. So this change adds CIBW_SKIP: "cp3*t-*" to skip free-threaded ABIs for now, and we can continue building on new regular CPythons while avoiding PEP 703 no-GIL builds.

thanks for catching this! looks like the nightly build has been failing for a while.

This fix looks good to me. I think we also need to apply the same change to svn-build-artifacts.yml

i tested it out on my fork, it works!

LGTM

[kevinjqliu]

trigger the nightly build, https://github.com/apache/iceberg-python/actions/runs/19039807174
and it works! https://test.pypi.org/project/pyiceberg/

Thanks for the fix @geruh
