feat: Add upcoming and live info to playlist videos

[absidue]

Description

Currently the live and upcoming status as well as the premiere date of playlist videos is not extracted. I choose property names that are the same as the ones in src/parser/classes/Video.ts.

Here are two playlists I found that can be used to test it (went to youtube.com/live, clicked through to the channels and looked for playlists with the live and upcoming videos in them):

Live: https://www.youtube.com/playlist?list=PL6NdkXsPL07IFb3kA-m9QNY8oUMctNM3i
Upcoming: https://www.youtube.com/playlist?list=PLT2PUxNJBoeONIclW0JlAhuX8j7umZKwZ
