Add the Welcome widget to the documentation

While it's arguably not the most useful widget, it's in the code, exported,
and can be seen by people; I feel it should be in the documentation. I've
ensured that it also links to Placeholder given it sort of is a Placeholder
and so people might arrive at it first and it makes sense to redirect them
to something more comprehensive.
