Pass --locked when installing rustfmt in integration tests

ytmimi · calebcartwright · commit 1a6146e53638 · 2022-06-14T15:23:33.000-05:00
There was recently an issue where `cargo install` was installing a newer
version of a dependency than the one listed in our Cargo.toml. The newer
version added deprecation warnings that caused our continuous integration
tests to break.

As mentioned in the `cargo help install` docs, passing the `--locked`
flag should force cargo to use the `Cargo.lock` file included with
the repository.
