demo: Switch to latest three.js & jsdelivr

We've switched from jsdelivr to unpkg a few years ago since jsdelivr at
the time didn't distribute three.js examples, but now it does and it's
much faster than unpkg, so it's time to switch back.

This also upgrades three.js to 174 which requires adjusting light setup.
