`egui::Table` has a weirdly specific default `max_scroll_height` set to
800.0. This means that even with `vscroll(true)` and `auto_shrink([_,
false])`, the table will not expend to the full available height. This
PR changes this value to `f32::INFINITY`. This makes it consistent with
the corresponding default value of `ScrollArea::max_size.y`, which is
where that `max_scroll_height` ends up being used.
