Fix typos in expression.py comment
Fixed two typos in the comment on line 47:
- "operatos" -> "operators"
- "expresion" -> "expression"
The comment now correctly reads: "Redefine operators that would only take a column expression..."
_TypeEngineArgument = Union[type[TypeEngine[_T]], TypeEngine[_T]]
-# Redefine operatos that would only take a column expresion to also take the (virtual)
+# Redefine operators that would only take a column expression to also take the (virtual)
# types of Pydantic models, e.g. str instead of only Mapped[str].
