[FR DatetimeV2] Year not recognized when month is spelled-out and "de" precedes the year

[srandal]

Describe the bug
In a date expression where the month is spelled-out and "de" appears between the month and the year, the hypothesized timex excludes the year.

Note: French speakers tell us that this pattern is natural, although it's more common not to include "de".

To Reproduce
Steps to reproduce the behavior:

1. Run SimpleConsole for fr-fr
2. Type "Je suis né le 23 novembre de 1987"
3. The hypothesized timex will be "XXXX-11-23"

Expected behavior
The timex should be "1987-11-23"

Sample input/output
Je suis né le 23 novembre de 1987

I found the following entities (3):
{
"Text": "23",
"Start": 14,
"End": 15,
"TypeName": "number",
"Resolution": {
"value": "23"
}
}
{
"Text": "1987",
"Start": 29,
"End": 32,
"TypeName": "number",
"Resolution": {
"value": "1987"
}
}
{
"Text": "23 novembre",
"Start": 14,
"End": 24,
"TypeName": "datetimeV2.date",
"Resolution": {
"values": [
{
"timex": "XXXX-11-23",
"type": "date",
"value": "2020-11-23"
},
{
"timex": "XXXX-11-23",
"type": "date",
"value": "2021-11-23"
}
]
}
}

Platform (please complete the following information):

• Platform: .NET
• Environment: console app
• Version of package: 1.7.0

@aitelint Can you take a look at this? Should be similar to a past fix.
