fix(rust-clap_derive): pin to 4.6.0 to match rust-clap and rust-clap_builder

rust-clap and rust-clap_builder were pinned to 4.6.0 (upstream Fedora
commit by Fabio Valentini, 2026-03-24), but rust-clap_derive was left at
4.5.55. This caused a cascading dependency failure:

  rust-clap 4.6.0 requires crate(clap_derive/default) = 4.6.0
  → rust-dlwrap requires crate(clap/derive) >= 4.0.0
  → rust-podman-sequoia requires rust-dlwrap+default-devel

Pin rust-clap_derive to upstream commit 4642814e (version 4.6.0,
"Update to version 4.6.0; Fixes RHBZ#2447042") to restore the lockstep
version alignment with rust-clap and rust-clap_builder.

Tested: built rust-clap_derive 4.6.0 locally, verified RPMs install in
mock chroot and provide crate(clap_derive) = 4.6.0 and
crate(clap_derive/default) = 4.6.0.
