[Update] Dungeon Player Limits

[Solo]

Stratholme, Blackrock Depths, Scholomance are now set to 10 player limit (5 before) and Blackrock Spire is set to 15 (10 before) just like the previous patch(es). Not gamebreaking but if players prefer patch 1.12.1 player limits for these dungeons, we'll revert the change.
