fix: sync Cargo.lock with craft-rtf's dependencies (#1086)

craft-rtf gained craft-flow, craft-metafile, craft-wordmodel and image in
its manifest, but Cargo.lock was not regenerated. Every --locked cargo
command then tried to rewrite the lock and failed, so all crate workflows
on main stopped during dependency resolution.

Regenerated with cargo metadata.
