[ModifyChapters] fixes (See desc)

* [docs] Fix typo
* Do not enable `sponskrub` by default
* Fix `--force-keyframes-at-cuts`
* Don't embed subtitles if the video has been cut. Previously, running `--remove-chapters` with `--embed-subs` multiple times caused repeated cuts and out-of-sync subtitles
* Store `_real_duration` to prevent running ffprobe multiple times
