Revert "Primitives now use color closures..." (#7710)

This temporarily reverts commit c5639cd9fa
(PR https://github.com/nushell/nushell/pull/7650). See
[here](https://github.com/nushell/nushell/pull/7650#issuecomment-1375036213)
for details; the PR is accidentally adding ANSI escape codes to strings
piped to externals.

I think we should revert the PR because we're only 1-2 days away from a
release; reverting it will give us more time to land+test a proper fix
in the next release cycle.
