Remove follow from commits by file (#20765)
The use of `--follow` makes getting these commits very slow on large repositories
as it results in searching the whole commit tree for a blob.

Now as nice as the results of `--follow` are, I am uncertain whether it is really
of sufficient importance to keep around.

Fix #20764
