[Feature]: Add descriptions to active effects

[nschoenwald]

What is the feature?

The active effects mostly don't have descriptions explaining what they do. You have to navigate to the parent item and read there, but it would be much better if you could see right in the active effect what the active effect actually does.
You shouldn't expect players to be able to read the active effect syntax on the effects tab.

What package are you reporting this for?

Dungeons & Dragons Dungeon Master's Guide

Could you provide a few examples? It is generally intended that non-trivial AEs have some context in their description, but we could have missed some.
