Subject: [PATCH] Simplify Cargo metadata for `publish = false` crates (#74)

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Therefore for crates that we do not publish, we can now remove both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`.
