For Competitive, mute LMS lines

As this is competitive, we don't need unnecessary voice-overs, gives away position when capping as LMS.

Enemy can not hear this as discussed different thread. An option to mute ALL voice overs would be great as it is both unrealistic, repetitive and annoying _ This is computer generated voices after all, and I don’t feel the immersion when getting spammed by the same voice overs for the fifth time

The thing is you cant hear any enemies rushing to you while you are trying to stay alive
