fix: add YouTube Studio to the list of clients

[LuanRT]

Description

As of December 16, YouTube Studio (Android) endpoints fail with a "Precondition check failed." message. If a newer version of the YouTube app is used then it throws a 404, indicating that it is now a requirement to use the correct client for YT Studio requests. I would say that's a bit of a bummer as we'll have to keep track of yet another client's version to make sure it doesn't get too outdated.
