Provides a `revalidateReason` argument to `getStaticProps` ("stale" | "on-demand" | "build"). - Build indicates it was run at build time - On-demand indicates it was run as a side effect of [on-demand revalidation](https://nextjs.org/docs/pages/building-your-application/data-fetching/incremental-static-regeneration#on-demand-revalidation) - Stale indicates the resource was considered stale (either due to being in dev mode, or an expired revalidate period) This will allow changing behavior based on the context in which it's called.
