chore: update rand to v0.10

This commit also cleans up the dev-dependencies that were already
part of the non-dev dependencies.

For Rust 1.64 (the current MSRV) the dependenct resolution for
the whole workspace doesn't quite work anymore. Instead of bumping
the version, it's solved on the CI level with removing the other
workspace members from the Cargo.toml before building.

Closes #397.
