fix: resolve 500 errors on youtube mix playlists for android

This commit downgrades the Android client version from 21.02.35 to 20.01.35
and adds necessary headers (X-Goog-Visitor-Id, X-YouTube-Client-Name, and
X-YouTube-Client-Version) to the resolve and search methods.

Testing confirmed that version 21.02.35 (and 20.51.39) returns a 500
Internal Server Error when fetching Mix playlists via the /next endpoint.
Downgrading to 20.01.35 restores functionality while remaining as current
as possible.
