[fix] nightly pypi build for pyiceberg_core (#983)

Follow up to #948 
I found a bug in the nightly pypi build where the version timestamp
changes within the jobs, causing a single run to push multiple versions.
This PR fixes the issue by setting the version timestamp once for the
entire workflow and then pass it down to individual jobs. This should
ensure a consistency version
