This PR introduces the React Router plugin in Nx.
The new functionality adds a react-router plugin entry into `nx.json`,
projects that are React-Router V7 via `react-router.config.(m|c)?[jt]s`
will have their targets inferred.
### Changes
Update the React plugin to have a react-router (RR V7) plugin export.
The RR V7 will only infer targets if we have a
`react-router.config.(m|c)?[jt]s` and also a `vite.config.(m|c)?[jt]s`.
Under the hood the RR V7 CLI uses vite for compilation.
That being said, apps are not limited to only use vite for RR V7. Should
you choose to use it the compilation will not be done via RR V7 CLI.
