Inspired by pyiceberg#1601 & https://github.com/apache/iceberg-python/blob/main/.github/workflows/nightly-pypi-build.yml

This PR adds nightly build of pyiceberg_core to testpypi.

I have successfully tested the github action on my fork by pushing to my own package,

I've also verified library versions locally

Rebased and addressed @Xuanwo 's concern with building wheels.

I'll set up trusted publishing for pyiceberg_core in testpypi when I get the proper permission :)

[Xuanwo]

Looks great to me. Let see how @Fokko and @liurenjie1024 think about this.

[liurenjie1024]

Thanks @kevinjqliu for this pr, LGTM!

Let's wait for a moment for @Fokko to take a look at this as he's more familiar with python.

[kevinjqliu]

Added trusted published to testpypi's pyiceberg-core (Thanks sung)

[Fokko]

This looks great, thanks @kevinjqliu for working on this, and @liurenjie1024 and @Xuanwo for the review 🚀
