Improve example TURN configuration

Should use quotes for turn_shared_secret value, or it will not work

Me and my firends met same problem on this spot. When you are not familiar with software it is difficult to find why it does not work, when there are no quotes there...

No new newsfragments found on this branch.

I do not think this fix worth mentioning anywhere. Just commit it please, so people have no problems setting up the turn? please

I don't think this requires quotes, by the way, unless your shared secret has some special characters in it maybe? By default YAML treats values as strings.

Additionally, please change your base branch to be develop, not master. Thanks!

A shared secret could technically have [ and ] characters in it, so adding quotes in that case would indeed be necessary. Doesn't hurt to add them I suppose.

I was wrong about this, doc only changes like this are fine to merge as is. 👍
