cargo-fmt version not displaying correctly

On the latest master (2c8b3bef2bb5d708e047afc4d0dadf0a85528470) the cargo-fmt binary isn't displaying it's version information properly.

This is what I get when running cargo-fmt

```
cargo run --bin cargo-fmt -- --version
cargo-fmt 
```

However we aren't seeing the same issue with rustfmt

```
cargo run --bin rustfmt -- --version
rustfmt 1.5.0-nightly (2c8b3bef 2022-06-21)
```
