📚 Description

seems like a relatively straightforward change

I'll open a similar one for netlify as well

having looked at both implementations, I'm not sure we need a manifest before merging this, but please do feel free to tell me if I've taken a wrong turn here.

Not (generated) manifest, but we need a configuration namespace manifest: { deploymentId } that stores VERCEL_DEPLOYMENT_ID.

Also can you please reopen on main branch? We can backport it later steps.
