Here is now the requests which will be made by the `onFetchPage` method of `YoutubeStreamExtractor`:
- the desktop API is fetched.
If there is no streaming data, the desktop player API with the embed client screen will be fetched (and also the player code), then the Android mobile API.
- if there is no streaming data, a `ContentNotAvailableException` will be thrown by using the message provided in playability status
If the video is age restricted, a request to the next endpoint of the desktop player with the embed client screen will be sent.
Otherwise, the next endpoint will be fetched normally, if the content is available.
If the video is not age-restricted, a request to the player endpoint of the Android mobile API will be made.
We can get more streams by using the Android mobile API but some streams may be not available on this API, so the streaming data of the Android mobile API will be first used to get itags and then the streaming data of the desktop internal API will be used.
If the parsing of the Android mobile API went wrong, only the streams of the desktop API will be used.
Other code changes:
- `prepareJsonBuilder` in `YoutubeParsingHelper` was renamed to `prepareDesktopJsonBuilder`
- `prepareMobileJsonBuilder` in `YoutubeParsingHelper` was renamed to `prepareAndroidMobileJsonBuilder`
- two new methods in `YoutubeParsingHelper` were added: `prepareDesktopEmbedVideoJsonBuilder` and `prepareAndroidMobileEmbedVideoJsonBuilder`
- `createPlayerBodyWithSts` is now public and was moved to `YoutubeParsingHelper`
- a new method in `YoutubeJavaScriptExtractor` was added: `resetJavaScriptCode`, which was needed for the method `resetDebofuscationCode` of `YoutubeStreamExtractor`
- `areHardcodedClientVersionAndKeyValid` in `YoutubeParsingHelper` returns now a `boolean` instead of an `Optional<Boolean>`
- the `fetchVideoInfoPage` method of `YoutubeStreamExtractor` was removed because YouTube returns now 404 for every client with the `get_video_info` page
- some unused objects and some warnings in `YoutubeStreamExtractor` were removed and fixed

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.
The strings playerJsUrl, sts and playerCode are now static in order to don't fetch again the JavaScript player at each time the signatureTimestamp is needed.
Catch every exception instead of only IOException and ExtractionException.
Add JavaDoc for fetchAndroidMobileJsonPlayer method of YoutubeStreamExtractor
Use the Android mobile API to get the itag 22 (720p with audio), removed when the content is protected by signatureCiphers.
Also use this API when they are OTF streams, to get the itag 17 and 36, low 3GPP quality streams but also the itag 139.
Update the web client version.
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.
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``
These exceptions are thrown on a test with the error messages text, because YouTube returns only "UNPLAYABLE" status in most error cases.
Tests are based with English strings, so changing the lang used by
extractor will throw the generic exception (ContentNotAvailableException).
YouTube changed the name of the chapters in the JSON from engagement-panel-macro-markers to engagement-panel-macro-markers-description-chapters, so extracting chapters doesn't work.
