[Pkg-rust-maintainers] Bug#1112591: please update crate clap to v4.5.46

[Peter Green]

I've prepared an update to the latest version of clap and uploaded it to experimental,
the following packages are updated in expermental.

clap 4.5.23 -> 4.5.48
clap-derive 4.5.18-> 4.5.47
clap-builder 4.5.23 -> 4.5.48
pulldown-cmark 0.10.3 -> 0.13.0
pulldown-cmark-escape 0.10.1 -> 0.11.0

The clap crates themselves are not semver-breaking, but the
pulldown-cmark crates are. I've gone through the reverse dependencies.
