Edit Level 2 Curriculum

[dealingwith]

Review existing curriculum for correctness

• [x] Does everything work in the latest version of Minecraft?
• [ ] Typos, missing instructions, etc.
• [x] #27
  • [x] Biome-specific stuff, for example
• [x] #26

Add stuff that's new since we wrote this curriculum

• [x] #32
  • [ ] We never had this section, so cover all of them
    • [ ] Zombies

    • [ ] Creepers
    • [ ] ...
  • [ ] Also "new" ones
    • [ ] Phantoms
    • [ ] Pillagers
    • [ ] Drowns
    • [ ] ...
  • [ ] Each additional dimension as their own thing:
    • [ ] Nether:
      • [ ] Ghasts
      • [ ] Pigmen
      • [ ] (the other kind of) Pigmen
      • [ ] ...
    • [ ] End:
      • [ ] Enderman
      • [ ] ...
• [ ] #36
• [x] #33
• [x] #35

Maybe for a lot of these, we can provide a brief overview, a tip or two, and then link out to the Minecraft wiki.
