Fix powerups in docs

[Andrew-S-Rosen]

In the docs, the powerups aren't actually applied because they are not done in-place. I've fixed this in the PR (and fixed the formatting in the rest of the .rst).

Apologies that I keep having to go back to fix linting errors. For some reason, I am getting the error below when I try to do any commits, and I haven't figured out why.

Fantastic! I made that change (previously modifications were performed in place) but forgot to update the documentation.
