[FR - DateTime] Recognize "mars" as a month

[alexathomases]

In fr-FR and fr-CA, the text “mars” is recognized as with TypeName “datetimeV2.date” and a null ResolutionValue, whereas other months (“avril”, “septembre”, etc.) are recognized with TypeName “datetimeV2.daterange” and complete ResolutionValue objects that include the appropriate timex.

1. DateTimeRecognizer.RecognizeDateTime("mars", "fr-fr")
2. See text “mars” is recognized as with TypeName “datetimeV2.date” and a null ResolutionValue

Expected behavior
It should return a model with TypeName “datetimeV2.daterange” and ResolutionValue with timex “XXXX-03”
