From https://en.wikipedia.org/wiki/NaN#Display, it says that apart from nan and -nan, we can also get NAN and even nan(char-sequence) from libc. In #11482, our conclusion was that we wanna normalize it in Redis to a single nan type, like we already normalized inf. For this, we also reverted the assert_match part of the test added in #11506, using assert_equal to validate the changes.
