Changes BackdropFilter out for ImageFiltered.

From the documentation for BackdropFilter:

This effect is relatively expensive, especially if the filter is non-local,
such as a blur.

If all you want to do is apply an [ImageFilter] to a single widget
(as opposed to applying the filter to everything beneath a widget), use
[ImageFiltered] instead. For that scenario, [ImageFiltered] is both
easier to use and less expensive than [BackdropFilter].

It looks a little different, though. You can play around with the child container opacity to change the look, but I found something I thought looked appropriate.

It's much more performant and doesn't have the strange flicker I was seeing while paging through my memories on my Android phone with the the BackdropFilter.
