Find a Replacement for Surge.sh

[sopa301]

Is the feature request related to a problem?

Surge seems to be having reliability issues. Even the main site is inaccessible from Singapore. It might be time to look for other deployment services.

If possible, describe the solution

We can consider Vercel, Netlify (it has a RepoSense deployment, though it fell out of favour because of usage limits), Github Actions.

Additional context

Somewhat related to #2194, but this time both the docs and site deployments are down with 503 errors.

EDIT: It's back up.

Currently, Vercel requires Pro Plan ($20 a month) for GitHub organizations but personal GitHub account is free.
We can set it up on our own forks but will need to create separate PRs for Vercel deployment previews.
Would need to explore other free options as a back-up plan.
