Move "@types/react" to dev dependencies

[MLoughry]

Issue: @types/react is listed as an optional dependency in addon-notes, which can cause type conflicts to any downstream consumer with a different types version

What I did

Moved the dependency to devDependencies

How to test

Build

Is this testable with jest or storyshots? No

Does this need a new example in the kitchen sink apps? No

Does this need an update to the documentation? No

Makes sense. I think it was here by mistake.
Thanks.
