Other changes:
- Renamed "getShortsWatchItem" to "getShortsVideoInfo".
- Fixed `ShortFormVideoInfo`. This never worked for me ever since it was introduced. Turned out it was just implemented incorrectly.
- Moved `basic_info` extraction to `MediaInfo`. Less of a pain to maintain as we only have to modify one file.
- Removed unneeded tsdoc comments.
- Fixed `Innertube#getStreamingData()`. Now it actually returns a deciphered format.
- Simplified some types.
