CPLAT-6477 Update Snippets for React 16

[joebingham-wk]

Motivation

The OverReact component snippets were still using component, UiComponent, and AbstractComponent, and UiStatefulComponent. We need to update those references to use the new V2 versions.

Changes

• Update the Dart2 snippets to use the new React 16 componentry.

So more generally,
I feel that because dart2 will be out completely and dart1 will be gone, we should remove all dart1 and dart1 and 2 snippets and only have these new snippets.

Additionally we should update the snippet names to be the original ones we had so they are clean again since these are currently ridiculous.

instead of ord2CStless just orStless
so take all the names from "Trigger - Dart 1/2 Compatible" here: https://github.com/Workiva/over_react/tree/master/snippets#available-code-snippets

We should also update the README to reflect only these new ones

I had thought maybe we should have a Component1 and Component2 set but after discussing with @greglittlefield-wf we decided we should only have Component2 snippets
