[5/N][Easy] fix typo for usort config in pyproject.toml (kown -> known): sort torch (#127126)

The `usort` config in `pyproject.toml` has no effect due to a typo. Fixing the typo make `usort` do more and generate the changes in the PR. Except `pyproject.toml`, all changes are generated by `lintrunner -a --take UFMT --all-files`.
