fix(files): correct a stale reference to the removed inner overflow

The sizing comment still credited `.document-table`'s own `overflow-x-auto`
for the horizontal scroll, which the previous commit removed in favour of the
caller's container.

 /* A preview table is data, not prose. A CSV can carry dozens of columns, so sizing the table to the
