useDateFormat: can't return 0 when the day is sunday and formatStr is 'd'

[JocelynFloresz]

Describe the bug

This PR #3001 leads to useDateFormat() can't return zero value.

return formatStr.replace(REGEX_FORMAT, (match, $1) => $1 || matches[match]?.() || match)

when the day is sunday , useDateFormat(useNow(), 'd') return 'd' instead of 0.
