Remove support for Node 14, raise minimum version to 16

[levibuzolic]

As discussed in #450, this raises the minimum node version support to 16 to fix some compatibility issues with the latest version of various dependencies.

I suspect the failing integration test is due to the SB 7 release that somehow broke stuff. Does it pass on master for you?

master doesn't pass locally anymore because Storybook 7 also requires Node 16 now.

@oblador Digging into the failure a little bit more, it looks Storybook 7 requires a web server because they've switched to usedusing JavaScript modules (.mjs) which can't be loaded from the local filesystem.

I quickly hacked in a http-server wrapper around the static build (though we might as well just run the storybook server directly) which gets a little further, however it looks like loki isn't compatible with Storybook 7, so that'll need to be fixed first.

@levibuzolic 0.31.2 is out now with storybook 7 fixes, could you please give it another try? 🙏

@oblador should be good to go now.
