- [ ] `./mach build -d` does not report any errors
I had hard time trying to compile rust-mozjs on my ubuntu machine, and I gave up. As this pr does not touch any source code, I expect it to be work.
- [x] `./mach test-tidy` does not report any errors
```sh
Checking the config file...
Checking directories for correct file extensions...
tidy reported no errors.
```
- [x] These changes fix#16149 (github issue number if applicable).
- [x] These changes do not require tests because it's trivial.
