Days difference calculation is wrong if the date format is DD-MMM-YY and year is more than 49(2049)

[gmprabu]

Describe the bug
const expInDays = dayjs('31-DEC-50').diff(dayjs(), 'day');
Above code considers year as 1950 instead of 2050. same code with 31-DEC-49 considers year as 2049.
DD-MMM-YY format days difference calculation works fine till 2049.

Expected behavior
It should calculate days correctly.
