chore(docs): use vercel ci again because GH secret problem on forks (#8142)

# Fallback to Vercel CI

Since we cannot share the vercel_token on forks we cannot deploy by
vercel CLI.
This PR reverts to the last working state by using vercel CI.

I will look into a fix with an npm script or a turbo config to ignore
builds on folder changes.
