Force npm + node versions for UI

[jsuereth]

This Fixes a few things in the build.

• First it forces a specific version for npm + node - the LTS version
• Second, it allows cargo to leverage docker in the event your local NPM fails (this may need to be configured better)
• Finally, this provides a better caching mechanism for cargo so we're not constantly farming out to npm. This is pretty critical for the docker fallback.

@jerbly Could really use your help trying this out.

If I've done this right, then you should have nothing to change because you're on LTS of node. Additionally, any machine that's on a different version will fallback to using docker to pull in the LTS version of node.

PTAL and let me know what you think!

@jsuereth - To have npm ci work I had to match the exact version of npm that's in the docker container, 11.6.2. This is a slightly old version. On 11.8.0, the latest, npm ci fails and therefore falls back to the docker container to build.
So, I would guess that we'll end up always building with the docker container since the version matching seems so exact.
