Maybe typo in Learn the Basic Concepts/Introduction to BTs

[zzsqwq]

I think the picture in https://www.behaviortree.dev/docs/learn-the-basics/BT_basics#fetch-me-a-beer-revisited section maybe have a error state.

This ForceFailure node should not be green (SUCCESS), it should be red (FAILURE). At the same time, if the ForceFailure node is green, then the Fallback node should also be green. Additionally, the subsequent CloseFridge will be executed again, meaning that the fridge will be closed twice. I don't think this is the expected behavior.
