CI(consolidated): drop pip show … | head -3, BrokenPipeError under pipefail

Run 25476176926 failed exit 120 because `pip show unsloth_zoo | head -3`
emits more than 3 lines, head closes the pipe, pip raises BrokenPipeError,
and `set -o pipefail` propagates that as a non-zero pipeline exit.

The `head -3` was cosmetic. Replacing with bare `pip show unsloth_zoo`
prints ~10 lines, no pipe, no surprises.
