fix: French number parsing ambiguity

[snowystinger]

Closes #7866

Discussed with Adobe's globalization team and french CLDR contributor. The consensus was that periods are ambiguous. France started to have recommendations against using periods as group separators in 1948, however, it was still taught in schools for a long time. As a result, depending on age or where someone went to school, they may expect it to be the decimal or they may expect it to be the group separator. To get rid of the ambiguity, it was recommended that we remove period as an allowed character and expand the group separator characters to allow all kinds of spaces so that they can easily be typed out on a standard keyboard.
