Mixes seems to be not given by YouTube anymore if you use a PENDING consent cookie value.
As mocks needs to updated, the test is always failing because of this change.
In order to use still use mocks with the generation of random strings in player requests, we need to use YoutubeParsingHelper.setSeedForVideoTests() method in every stream test.
This method is needed for YouTube stream tests, because when all YouTube tests are ran, the signatureTimestamp is known (the sts string) so a different body than the body present in the mocks is send by the extractor instance.
As a result, running all YouTube stream tests with the MockDownloader (like the CI does) will fail if this method is not called before fetching the page of a test.
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
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
