Subject: [PATCH] build: skip deleted files in the changed-file ruff format
 check

`make lint` hands every path in the diff against the base branch to `ruff
format --check`, including the ones the branch deleted, so any branch that
moves or removes a file under `litellm/` fails the gate with "No such file or
directory" instead of a formatting complaint.

test-linting.yml already filters those out with `--diff-filter=ACMR`, so the
Makefile was the half that drifted. Match it.
