MDL-50963 lang/en/grades.php: Improve bad grade error message
The error message received when inputting a grade value that is too
low indicates that zero is a valid grade value. This is incorrect as
the lowest valid grade value is 1. This updates the error message to
indicate the minimum acceptable grade value is 1, not 0.
