ci: update ci for unused dep

[alxiong]

This PR:

Fix CI failure for periodic check: https://github.com/EspressoSystems/jellyfish/actions/runs/8863541950/job/24337714873 (which always notify me on weekend 😢 )

How to test this PR:

since we didn't install cargo-udeps in nix shell, I was using my local exec, and I got:

└─○ cargo-udeps udeps --workspace --all-targets --features 'test-srs test-apis bls schnorr gadgets'                      
All deps seem to have been used.

Should we consider adding udeps in nix environment as well. Maybe not in this PR

Yah we should. We could do it later.
