Incorrect regex pattern in decade_format in fr-fr/date_time.json

[coderabbitai]

An incorrect regex pattern is present in the decade_format in fr-fr/date_time.json. The pattern [2-6|8] incorrectly uses the | character inside a character class. It should be corrected to [2-68] to match digits 2 through 6 and 8.
