Also update the mock of the next InnerTube endpoint response of the
YoutubeStreamExtractorDefaultTest.DescriptionTestUnboxing test class with an
attributedDescription instead of a regular description
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.
Replaces mix tests based on a strange mix type RDQM{videoId} (only reference I could find is https://github.com/ytdl-org/youtube-dl/issues/26228) and with an invalid video id of 13 characters (the first two characters were QM, but even after removing QM there still wasn't a video available at that id).
Also updates mocks.
* Deprecated Utils#UTF-8; see StandardCharsets
* Added more helpful methods to ``ExtractorAsserts``
* Use parameterized (cool new) tests
* Restore functionality of some tests + updated mockdata
* Other code cleanups + Sonarlint improvements
Without removing RunWith and SuiteClasses annotations (and the corresponding imports) in YoutubePlaylistExtractorTest and YoutubeMixPlaylistExtractorTest, some mocks cannot be generated, so the CI fails because of the missing mocks. Mocks of workings tests have been also updated.
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
