Add `--no-index` to CI's git-diff check on generated files (#1428)

`git diff` does not work by default on untracked files. Since the
function `_check_file_not_changed_by` stores the new generated file in
an untracked file, `git diff` was not catching any modifications in
the new generated file. This commit adds the flag `--no-index` to make
`git diff` work with untracked files.
