Feat: Need to bring in unified versioning for React and other Platformy stuff

[dmikey]

The cool thing about being able to pick each technology on a project by project basis is that we can be super flexible, however, we've got a bunch of different projects where the React versions, and thus the APIs used across the projects maybe a out of sync.

Would be nice to have a set of standard versions in a central repo.

We have a situation like this in nodesource/elements, and what happens in the end is basically that the version of elements becomes outdated, and when you need one new feature from elements you have to upgrade all of the things, which doesn't always work timing wise.

It would be nice still to have up to date versions of react across all repos, or, when you notice that one version is api incompatible (as I recently noticed we can't use hooks in accounts-ui) to open an issue and prioritize it for tech debt.
