Tutorial Update

Fixed two things in the tutorial:

• The villager counter required to complete the tutorial has been fixed. Now, the tutorial correctly validates if you have 4 villagers or more, instead of less than 4.
  
• The note stating that bushes take 5 minutes to regrow was incorrect, as the actual regrowth time is 3 minutes. I had changed this in a previous patch but forgot to update the tutorial info, which is now fixed.
  

I hope all the bugs are now resolved so that I can focus on adding new gameplay elements to the game.
