feat: Add lenient validation of the date parsing

[8o8inCodes]

This pull request is aiming to add validation to the lenient dates (Issue)

Current issue:

dayjs('2025-13-36T14:19:39') // note that the month is 13 and day is 36
// output: Thu, 05 Feb 2026 12:19:39 GMT
// which calculates a new date using the remainders from days and months.

This PR adds another option called "lenientValidation", where if you will submit such case, you will get a new dayjs invalid instance.

const badDate = dayjs('2025-13-36T14:19:39') // note that the month is 13 and day is 36
badDate.isValid();
// output: False

If you have better name for this option, feel free to suggest. I hope this PR is helpful.
