Slideshow direction naming somewhat confusing

[sukram230799]

While playing around with the slideshow, I stumbled over the Direction settings. Currently, the UI shows Forward and Backward.

From my first assumption for a slideshow, this would mean forwards/backwards through time, especially in the German translation. However, it is currently dependent on the album order and will either be Descending- or Ascending order through that album.

immich/web/src/lib/components/slideshow-settings.svelte

Lines 29 to 31 in 6729782

	[SlideshowNavigation.Shuffle]: { icon: mdiShuffle, title: $t('shuffle') },
	[SlideshowNavigation.AscendingOrder]: { icon: mdiArrowUpThin, title: $t('backward') },
	[SlideshowNavigation.DescendingOrder]: { icon: mdiArrowDownThin, title: $t('forward') },

Maybe we could use another label for it (Downward/Upward or Top down/Bottom up or even Ascending order/Descending order) to better communicate what it does. What are your opinions/suggestions?

Thanks, Markus
