New manga info expander (#5771)

* Replace "More" with Arrows

We used to have arrows but it was set away from the description which took a lot of space.

It was changed to "More" text, but with the recent design changes I think it'd look better to get a mix between them both.

* Properly align icons

* Expand support to Tablets

Get it... expand... hehe 😎

* Fix expanded width

Also fixes so that the constraint for the toggleLess is dependant on the right thing

* Give info toggles its own space

Uses its own margin now to push info rather than just being attached as a info margin.

* Remove weird duplicates I did not add

I did not add these but I don't see a reason to keep dupes

* Add bottom scrim

* Change to centered arrow under info

Anyone wanna experiment/build on top off then feel free to tweak

* Add background glow to icon for contrast
