[Lyrics Plus] Add translate button for multi-languages

📝 Provide a description of the new feature

Some lyric platforms like Musixmatch have a function that has the original language lyrics and one line of the translated lyric at below.

And seems like Spotify is ready to add this function to its app. (The Android version already has this function, but the translated lyrics are still very few)

Seems like now we have the Chinese convert button to convert Simplified/Traditional Chinese. Maybe we can add this function to that button and add the option to show one line or two lines of two languages of lyrics.

➕ Additional Information

The android version's funtion shows the original and translated lyrics:
