[YoutubeBridge] Fix parsing author name breaks the bridge

Browse source 
The author name is parsed by searching a string within the entire
HTML document:

$author = $html->innertext;
$author = substr($author, strpos($author, '"author=') + 8);
$author = substr($author, 0, strpos($author, '\u0026'));

This solution will return big portions of the HTML document if
the strpos function returns zero (not found).

This commit replaces the previous implementation by searching for
a specific script tag and making use of the JSON data inside it.
