`package.rust-version` will gain support for an `"auto"` value, in addition to partial versions.
On `cargo publish` / `cargo package`, the generated `*.crate`s `Cargo.toml` will have `"auto"` replaced with `rustc --version`.
If `rustc --version` is a pre-release, it will be left as unspecified with a warning.
If `rustc --version` is a pre-release, publish will fail.
`cargo new` will include `package.rust-version = "auto"`.

- There is little reason to select an MSRV higher than their Rust toolchain
- We should still be warning the user that new dependencies are available if they upgrade their Rust toolchain
- This comes at the cost of inconsistency with `--ignore-rust-version`.
- Nightly `cargo publish` with `auto` fails because there isn't a good value to use and this gives us flexibility to change it later (e.g. just leaving the `rust-version` as unset).
## Ensuring the registry Index has `rust-version` without affecting quality
