nonreactive examples for hooks were not compilable as written

[rogusdev]

My code was out of date, so I missed b6d3da2 -- but I still caught one more, and added an example. Also tweaked the comments.

Notably: for the example, I did not call &*res.read_unchecked() as the docs suggest on https://dioxuslabs.com/learn/0.5/reference/use_resource -- instead choosing to simply do res(), which definitely works. If the longer syntax is preferred / recommended, I would like to update my example to keep best practices in all places, but I'd also like to hear why, thanks.

Thank you! Non reactive props are also documented better after #2460
