Spelling mistake for Json parsing exception for score with missing name or objective

The bug

The Json exception that is thrown when a score component has no name or objective key is misspelled. It should say "at least", not "a least".

A score component needs a least a name and an objective

How to reproduce

/tellraw @s {"score":{}}
