Update client version, fix some tests, update mocks and do some improvements

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
