[pickers] manual year addition only allows when 3 digits entered

Steps to reproduce

Steps:

1. Check issue on link: https://stackblitz.com/edit/react-omshxuse?file=Demo.js

Current behavior

When I manually type date like this 11-11-0111 it accepts 0111 as an year. If I enter 11-11-0001 it detects this as null date.

Expected behavior

I want to ensure that I catch in the validation a date like (11-11-0001, 11-11-0011, 11-11-0111) as invalid. Right now it considers it as null and I am able to save as null. How can I catch this such that if the year entered is not up to 4 digits (e.g. four digit years like 11-11-1111 or 11-11-2024), then the date is considered invalid? How can I achieve that?

That's a great question.
We do not fire the onChange for year values with less than 3 characters. My guess is that we do not any value with less than 3 chars a valid yearpart, but @LukasTy is the expert here. Could you elaborate on this @LukasTy ?
