DashboardWidget and Widget Component class names mismatched

[Ralkage]

Bug Report

I was trying to develop a new widget for the Admin Dashboard page and noticed a few minutes ago that the following classes are mismatched:

https://github.com/flarum/core/blob/master/js/src/admin/components/Widget.js#L12 the class name should be" Widget" to match the file name and with https://github.com/flarum/core/blob/master/js/src/admin/components/DashboardWidget.js#L12 the class name should be "DashboardWidget" instead of "Widget".

Looks like this has been here since it's conception in Beta 8 🙈

They pretty much have the same code despite the class name differences in both JS and HTML class attributes.
