[ENHANCEMENT] LEGUP puzzle editor documentation

[charlestian23]

Describe the current behavior of what you're trying to improve. If your enhancement request related to a problem, please also describe the problem.

There currently does not exist documentation on how to use the puzzle editor.

Describe the improvement you'd like

Like the proof editor, we should add a tutorial for how to use the puzzle editor. We could potentially add it on to the same place the proof editor tutorial is located: https://github.com/Bram-Hub/Legup/wiki/LEGUP-Tutorial

Describe alternatives you've considered

We could also split the proof editor tutorial and puzzle editor tutorial into two separate pages and then make them clearer on the Wiki sidebar.

Closing since @jadeandtea completed the documentation and I reviewed it.
