Do not change architecture of packages during rebuilds

Hi All, As you might have noticed, Python 3.13 is moved to [core]. Just like with the move of staging to testing we can't move a package because it changed architectures and hits a dbscripts bug. [1] Please don't do this until the bug is fixed :) [1] https://gitlab.archlinux.org/archlinux/dbscripts/-/issues/57
