misc,tests: Remove zip step from Workflows (#1048)

This is not needed with upload-artifact v4 directories are archived and
compressed by default.

This zip step was also causing Daily/Weekly test failures due to not
running `apt update` before the `apt install` for the zip utility. Ergo
this patch fixes these errors.
