Use again www.youtube.com and music.youtube.com domains instead of youtubei.googleapis.com domain because it spoofs more a web client of YouTube or YouTube Music and may reduce Google's detection of NewPipe Extractor users.
This commit updates mocks and reenables the test invalidId of the NotAvailable class of the YoutubePlaylistExtractorTest class beacuse with the youtubei/innertube API, it returns "Not found" and doesn't redirect to the YouTube homepage.
The expectedMetaInfo test of the MetaInfoTest class of the YoutubeSearchExtractorTest class was broken because YouTube removes the vaccine progress link of the WHO from the meta info so this commit removes it and the test is now passing.
Add the origin and the referer headers with the https://www.youtube.com value for YouTube JSON POST requests.
Don't add the consent cookie header for the requests which use the youtubei/innertube API because it's uneeded.
Fix some tests and update YouTube mocks
Get the real name of the uploader (for autogenerated channels and music artist channels), like before the migration to the JSON pbj.
Do some other improvements, especially reformatting some code to be in the 100 characters line limit and use final where possible.
Change the domain from music.youtube.com to youtubei.googleapis.com.
Use a lightweight request to check if the hardcoded YouTubeMusic keys are valid. Increase the length of the response to 500 because if the key is invalid, the length of the response returned is higher than 250 and the response when the key is valid is higher than 1500.
Format the YoutubeMusicSearchExtractor file.
Update YouTube web client version and mocks
Add getSearchParameter, a new method in YoutubeSearchQueryHandlerFactory class which returns the params field for a search, or an empty string if there is no one.
Update mocks of YoutubeSearchExtractorTest.
Without this commit, the n param is only decrypted for streams extracted in getVideoStreams (so only for streams in the formats object of the player response).
To fix ``java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String[] java.lang.String.split(java.lang.String)' on a null object reference``
