Changed fr.dat to make babel stop breaking

As in c2cb6e3e1db6a914eaa57c9ebdeae4acc80e387b, I modified the plural data manually to replace a range_list of length 1 with a single range. I loaded the data with

    import pickle
    from third_party import babel
    data = pickle.load(open("third_party/babel/localedata/fr.dat", "rb"))

then changed `data['plural_form'].abstract` from

    [('one',
      ('and',
       (('relation',
         ('within',
          ('n', ()),
          ('range_list', [(('value', (0,)), ('value', (2,)))]))),
        ('isnot', (('n', ()), ('value', (2,)))))))]

to

    [('one',
      ('and',
       (('relation',
         ('within',
          ('n', ()),
          ('range', [('value', (0,)), ('value', (2,))]))),
        ('isnot', (('n', ()), ('value', (2,)))))))]

and wrote it back out:

    pickle.dump(data, open("third_party/babel/localedata/fr.dat", "wb"))

Test Plan: Loaded /?lang=fr-FR locally, which previously failed.
