chore: fix NPM publish flow

[jescalada]

Fixes #1334.

What was missing in #1351 is fixing the Node version as shown in the NPM guide sample snippet.

The rc.4 is successfully published on NPM - I added publish on PR for commit 4ebf646 and then removed it.

Review CI failure then we can merge this

Looks like this was due to a hiccup with the Docker rate limit, unrelated to the Node version change in the PR:
