formatting: Run Python formatter at 3.8

It looks like yapf formatter invoked with `scripts/formatting` uses
system Python 3 version which yields different results for Python 3.11
and Python 3.8. Buildkite seems to use Python 3.8, so this leads to
different behavior locally and remotely.

For now, I'm fixing the current lint warning that prevents submitting near#9157
but ideally we would fix this by either making sure formatting is the
same across versions or by fixing the Python version used in the
formatting script.
