Simplify Cargo metadata for publish = false crates

As of Cargo 1.75 the `version` property in `Cargo.toml` is now optional, and if omitted is the same as having specified `version = "0.0.0"` and `publish = false`: https://github.com/rust-lang/cargo/blob/master/CHANGELOG.md#cargo-175-2023-12-28 https://doc.rust-lang.org/cargo/reference/manifest.html#the-version-field Therefore for crates that we do not publish, we can now remove both the `version` and `publish` properties, avoiding the need for the fake `0.0.0` version that differs from the actual buildpack version in `buildpack.toml`.
