To Reproduce

1. Run pnpm build

Current vs. Expected behavior

Current behaviour

Following either the .107 or .108 canary, we started seeing errors when server actions were called with after inside them while rendering a PPR page when building the app.

Error: Route / needs to bail out of prerendering at this point because it used unstable_after.

Expected behaviour

This works as before (as in dev) where app builds successfully.

Actually, it's not a bug. The action calls are missing an await so it makes sense that this would error in some way. Adding it fixed it!
