Subject: [PATCH] fix: Do not append query params `quality=medium` to videos
 that are about to premiere (#5755)

* fix: Do not append query params `quality=medium` to videos that are about to premiere

Video premieres do not have `audio_streams` and they aren't `video.live_now == true` either,
therefore we skip the checks that are made for older videos (`if audio_streams.empty? && !video.live_now` closure)
if the video is a premiere.

This commit also adds the `microformat` field to the `info` instance
variable of the `Video` struct, since it's needed for the function
`Video#premiere_timestamp : Time?`. This is more like a quick fix than a
proper fix because in `Invidious::Videos::Parser#parse_video_info`,
`premiere_timestamp` is gathered from the `microformat` JSON Object but
is used to set the `published` hash key for the `params` variable.

The parsers and structs really need a rework :/

* Revert "fix: Do not append query params `quality=medium` to videos that are about to premiere"

This reverts commit 5cfc8dace82590ea6a41c849c9c39b1b7ba95fe7.

* chore: build premiere_timestamp using video_type and published time
