**Describe the bug** On my desktop, when I run the command ``` cargo +stable fmt --all -- --check ``` I always get the warning ``` Warning: Unknown configuration option `rust-version` ``` When I run the command ``` rustfmt --help=config ``` I could not find a configuration option called `rust-version` I am not sure whether it is a bug or my problem. **To Reproduce** Run the command ``` cargo +stable fmt --all -- --check ``` **Expected behavior** Remove the warning. **Additional context** [Developer's guide to Arrow Rust.](https://github.com/apache/arrow-rs/blob/794929835dd32f2c2e6897d7f606606e3e5aab29/CONTRIBUTING.md#:~:text=cargo%20%2Bstable%20fmt%20%2D%2Dall%20%2D%2D%20%2D%2Dcheck) -- This is an automated message from the Apache Git Service.
