document removed features: night mode and gestures

[david-allison]

Adds a 'removed-features' page

• Fixes https://github.com/ankidroid/Anki-Android/issues/14921
• Fixes https://github.com/ankidroid/Anki-Android/issues/15080

I am (lazily) awaiting CI to test the rendering of the page.

I suspect that we'll want to bikeshed the color inversion CSS, if this takes a long time, let's split it out into another PR

filter: invert(1) might be a better recommendation, as it means users do not need to concern themselves with HTML color codes. I don't know whether this fully approximates our pervious inversion code.

• CSS highlighting didn't work (not the end of the world)
• NOTE: may want another admonition: https://docs.asciidoctor.org/asciidoc/latest/blocks/admonitions/

I thought about having version-based structure ("removed in 2.17") vs what you have done which is feature-based structure ("this thing was removed" - then note what version). I don't think it really matters, and feature-based works well for me

I like all the in-document structure. So as far as I'm concerned this is 99.9% there

I also considered it. I like

1. Being able to link to a section and getting all the information, rather than needing to scroll to a heading
2. Removing a nested heading

Going with it - fixups are easy if needed as this stuff publishes fully-auto. Awesome to close off some easy ones!
