YYYY-MM-DD interpreted as YYYY-DD-MM

YYYY-MM-DD interpreted as YYYY-DD-MM for arabic, but also looks like in other languages which prefer DMY order, but this looks strange -- it seems that if year is first, then we should ignore DMY / MDY and just use YMD for all locales?

Examples:

>>> dateparser.parse('2023-11-08', languages=['ar'])
datetime.datetime(2023, 8, 11, 0, 0)

>>> dateparser.parse('2023-11-08', languages=['en'], region='GB')
datetime.datetime(2023, 8, 11, 0, 0)

>>> dateparser.parse('2023-11-08', languages=['en'], region='US')
datetime.datetime(2023, 11, 8, 0, 0)

>>> dateparser.parse('2023-11-08', languages=['en'])
datetime.datetime(2023, 11, 8, 0, 0)

Side note: in reality US also has MDY date order, so if we'd interpret en as en-US and if it had MDY set, then we'd parse a lot more dates incorrectly.

Start by reproducing the four dateparser.parse examples in the issue and trace how locale-specific date ordering is selected for Arabic and English regions. Compare the current results with the requested behavior: an input written as YYYY-MM-DD should consistently produce the corresponding year, month, and day across locales. No file or test path is named in the issue.
