Revert "Add new workflow changes for 2025 January"

This reverts commit 817ce2f3.

This was pushed and merged in a rush without Go team agreement or consensus, based on false premises where even the DEP it is based on does not have any mention of there being defaults preferences for these changes, where there's been recorded objections in general in the Debian project at large in the past, and where even existing practice (as analyzed by the same author) does not support these defaults being the majority in use.
