Allow typing French numbers with coma instead of point

When we enter data in the Numbers columns of the French version, even if it shows the decimals with a coma, we can’t actually type them with a coma when entering data.

E.g. My number keyboard would enter: 250,99 but the column won’t allow the coma, so I need to type 250.99 – then the column would show 250,99. So it slowing down the data entry.
