[FR - DateTime] Recognize year number

[quangngoc]

Describe the bug
In French, it's common to use "mil" instead of "mille" to denote years in official documents. For instance, "deux juillet deux mil vingt deux" should be interpreted as July 2, 2022. However, this is not recognized correctly

To Reproduce
Steps to reproduce the behavior:

1. Try DateTimeRecognizer.RecognizeDateTime("deux juillet deux mil vingt deux", "fr-fr")
2. Only "deux juillet" is recognized

Expected behavior
It should return 2022-07-02
