Invoke previously defined command instead of running node directly

[Josh-Cena]

Summary

Fix #10972; supersedes #17642

Motivation

It's generally recommended to avoid running node, especially when using Yarn PnP since it simply doesn't work. For any slightly non-trivial task, including starting a server, abstraction with a custom command is recommended, and since we already have a command, let's use it instead.

Also, the problem with having this kind of tutorial on MDN is that the web dev stack and practices renovate almost every six months, so it's super hard to keep the content up to date...

Very true — and unfortunately that problem isn’t unique to this particular article; especially in the Learn subtree, we’ve got a number of guides which just inherently have a pretty short shelf life built in.
