Allow typing date in Nepali date field

[ajiragroup]

Currently, the date value is not registered until we manually click the date in the date picker. In the default date picker (AD), we can do any of the following:

1. Type in format: 20240102
2. Type in format: 2024.01.02
3. Type in format: 2024-01-02
4. Navigate to correct month and Click on the date manually
   Anything works.

But in Nepali date field, only one option works: navigate to month and click on date.

If we type in the date value, the corresponding AD date is not converted. Can you add this functionality to make date field more interactive?
