AUDIO: Remove "Sound Effects Volume" from menu screens

Per title, remove “Sound Effects Volume” from menu screens (i.e. don’t have sound effects play in menu). I usually always turn music to 0 for games because I’m usually talking to friends in Discord etc while playing. This also removes music from menu screens. Sound Effects however play in AoE 4 on the menu screen - the same “grr grr grr” people growling in the background of menu screens or whatever they’re grunting. I enjoy sound effects in-game, but not in menu. Please remove the sound effects from playing in-menu so I can leave them on
