clippy --fix now errors on untracked files

[bryanlarsen]

Summary

After upgrading to rust 1.67.0 clippy --fix now fails if you have any untracked files in your git repository. I now have to pass the --allow-dirty flag to use clippy --fix. I didn't have to do this in rust 1.66.0.

If this is a deliberate change, I suggest adding an --allow-untracked flag to clippy --fix so that we can get the old behavior back.

Reproducer

reproduce:

cargo new foo
cd foo
git add .
git commit -m "Initial commit"
touch bar.txt
cargo clippy --fix

I expected to see this happen: Success

Instead, this happened:

error: the working directory of this package has uncommitted changes, and `cargo fix` can potentially perform destructive changes; if you'd like to suppress this error pass `--allow-dirty`, `--allow-staged`, or commit the changes to these files:

  * bar.txt (dirty)

This'll be from rust-lang/cargo#11400 (the --fix functionality is powered by cargo fix)

It'd be good to add a comment/open an issue there if this has hit your workflow
