Revert "Enable grep_linter to use -a (#144589)"

This reverts commit 3c55669b8814237e018a613a494564da5bea9f15.

Reverted https://github.com/pytorch/pytorch/pull/144589 on behalf of https://github.com/clee2000 due to the line parameter is kind of important and -a is not as important as I thought it was so I'm going to revert this ([comment](https://github.com/pytorch/pytorch/pull/144589#issuecomment-2608349155))
