feat(YouTube): Remove video chapters from seekbar

[n1cKz1]

Feature description

This patch would completely disable video chapters from showing up on the seekbar.

Motivation

1. Seekbar feels cluttered with too many chapters
2. Chapters have a "feature" where if you try to seek forward or backwards in a chapter it randomly auto-drags you back to the beginning of your current chapter or forward to the beginning of the next one. This is very annoying especially since YouTube has recently been auto-generating chapters for many videos on their platform, so it often feels like you can't even seek properly anymore. I've created another request for a patch to disable this behavior alone in the past but I closed it in favor of this.
