Update some misc dependencies (#11820)

* Update some misc dependencies

We don't really update that often, but it's probably best to update
rarely as opposed to never. This commit runs

    cargo update -p clap --aggressive

and then vetted the results. No concrete purpose here other than keeping
up-to-date to avoid some bug that was fixed years ago biting us at some
point.

* Downgrade rustix back to 1.0.8
