`isDate` validation is broken after upgrading to validator v13.11.0 about validator.js

Thanks, @brunoabude! Just submitted a pull request that would solve the timezone issues as you suggested.

Looks like the Date constructor is now using the ISO8601 date format without the time zone offset info, which causes it to be interpreted as UTC+0 and can fail the comparison of .getDate() and the parsed day from the date string (which could be safely assumed to be in local time, i guess?)

To keep the same behaviour as the previous version, T00:00:00 could be concatenated to the isoformat, which will cause it to be interpreted as local time. As demonstrated here

validator.js/src/lib/isDate.js

Line 68 in f074abd

return new Date(`${fullYear}-${dateObj.m}-${dateObj.d}`).getDate() === +dateObj.d;

Can confirm this was breaking for us too. It was tricky to debug cuz it worked in our CI just fine but was failing locally. Rolling back to 13.9.0 for now to solve the issue until the fix goes in.
