fix: update repo URL to be the soon-to-be archived repo for React packages

[nicholasrice]

Description

This change updates the git repo link in all React packages to point to https://github.com/microsoft/fast-react/. This new repository will serve as the React archive project. Setting the git url in package.json will update the link in the NPM registry so that the deprecated packages will point their source to the deprecated repository.
