You can add notes about animations yes, but preferably nothing too superfluous. I personally didn't bother with animation names since a lot of them are really similar or obscure and are hard to name, and for the most part I assume people can figure out how to animate them.
But yeah, if you want to do that feel free, just try not to add any unnecessary text or weird fonts like in the second one you linked.
