Remove trailing tabs after license to avoid mlx-lm.convert errors

With these tabs existing, mlx_lm.convert throws an error during conversion due to an error with YAML parser. By removing these tabs, mlx_lm.convert does not throw an error anymore, allowing users to make MLX quants without any additional hassle.
