Describe the bug

Executed below code.

const dayjs = require('dayjs');

console.log(dayjs('2024-00-02T04:57:02Z').isValid());
console.log(dayjs('2024-02-31T22:03:08Z').isValid());
console.log(dayjs('2024-02-31T22:03:08Z', 'YYYY-MM-DDTHH:mm:ssZ', true).isValid());

result

false
true
true

February 2024 has only 29 days, not 31.
dayjs('2024-02-31T22:03:08Z').isValid() should return false.

Expected behavior

false
false
false
