forest_fire notebook broken with Mesa 4

[Vanya-kapoor]

The Forest Fire notebook is broken with Mesa 4 due to several deprecated
or removed APIs.

Errors when running the notebook:

• from mesa.batchrunner import BatchRunner — BatchRunner removed in Mesa 4
• fire.run_model() — deprecated, no longer works
• fire.dc — attribute renamed to fire.datacollector
• df.BurnedOut — column name is "Burned Out" in batch_run output

Environment:

• Mesa 4.x
• Python 3.11
