Auto merge of rust-lang#12382 - Alexendoo:macos-ci, r=flip1995

Bump macOS CI version to 13

I looked into the random failures we've been getting on macOS CI, not entirely sure what is going on but it seems to be an issue out of our department. A [plain driver](https://github.com/Alexendoo/rust-clippy/blob/314425001df19a82c295952b26664704d06e9348/src/driver.rs) being ran on the test files [without `ui_test` or any special flags](https://github.com/Alexendoo/rust-clippy/blob/314425001df19a82c295952b26664704d06e9348/src/driver.rs) hit the same issue

It didn't occur on `macos-13` the few times I tried it though so let's upgrade to that. [The current `macos-latest` refers to `macos-12`](https://github.com/actions/runner-images?tab=readme-ov-file#available-images), later this year it will refer to `macos-14` which runs on `aarch64` so specifying the version for our x64 macOS tests will also save a future headache
