update peertube instances list

APK testing

I did not test nor build the apk but it's minor change and the added url is correct

Due diligence

• I read the contribution guidelines.

If someone wants to know the rationale for the removal of two instances:

• peertube.live: no HTTPS (all videos on this instances do not work, only federated ones work), uses Google Analytics (even if it's not loaded in NewPipe, we don't want to promote instances using such tools).
• peertube.video: 503. We might want to check if it's not up again before the next release

Hey, thanks so much for thinking to include TILvids.com in the official list! I'm a big fan of NewPipe, and definitely recommend it to anyone looking to watch TILvids content on their Android device. Cheers!
