'YYYY' results in missing leading zeroes when year <1000

[Sharparam]

Describe the bug
If the year component of a date is less than 1000, the leading zeroes are omitted when trying to format the year with 'YYYY'.

E.g.:

dayjs(Date.parse('0001-01-01')).format('YYYY-MM-DD') //=> '1-01-01'
dayjs(Date.parse('0010-01-01')).format('YYYY-MM-DD') //=> '10-01-01'
dayjs(Date.parse('0100-01-01')).format('YYYY-MM-DD') //=> '100-01-01'

Expected behavior
'YYYY' in the format string should place leading zeroes to make sure the year takes up 4 digits in the output.

E.g.:

dayjs(Date.parse('0001-01-01')).format('YYYY-MM-DD') //=> '0001-01-01'
dayjs(Date.parse('0010-01-01')).format('YYYY-MM-DD') //=> '0010-01-01'
dayjs(Date.parse('0100-01-01')).format('YYYY-MM-DD') //=> '0100-01-01'
