## Message

```
Use arithmetic expansion instead of `expr` in `./script/clear-target-dir-if-larger-than` (#47298)

Fixes CI failures when the target dir is 0GB in size, which causes
`expr` to output a non-zero exit code per the posix spec.

See exit status section of
https://www.man7.org/linux/man-pages/man1/expr.1p.html
