Good catch! It looks like this also fixed an error in the snapshot test for useNumericLiterals https:/biomejs/biome/actions/runs/7427689816/job/20215337416?pr=1447#step:5:1451. If you run cargo insta review it should show you the diff between the current and the new snapshot, and you can accept the new one through that interface (by pressing a). That will update the test and make it pass here on CI.

In general, you should also use just ready when you're ready to open a PR, which will run effectively all of the CI tests on your machine before pushing so you can catch this feedback earlier and update more quickly.

Sorry, I don't really feel comfortable installing 8 command-line tools to run the testsuite. I've updated the snapshot test using the snapshot that got emitted using cargo test. I'll leave it to CI to check if everything works now.

Also I've rebased because I accidentally used the wrong author info.
