community/dendrite: increase allowed file descriptors, add TURN as a soft-dependency
Hi, this is my first time making a PR to Alpine. I think I have read the relevant documentation on how to do a proper change and I have tried to follow the guidelines. The commit message may be a bit too long however.
If I have done anything wrong, please, point it out! It is also my first time using Gitlab.
