Prepare the Rust workspace for a release.

Preparing the release updates the version of each crate in the workspace and of the intra-workspace dependencies. The version field in the packages table of each Cargo.toml file in the workspace is set to the supplied version. The version field of each dependency, build-dependency and dev-dependency that is otherwise identified by a workspace-relative path dependencies is also set to the supplied version (the version filed will be added if it isn’t already present).

This implements the prepare step for semantic-release for a Cargo-based Rust workspace.
