chore: Script the generate of Verdaccio's database to skip slow publish

[snowystinger]

Closes

getting our packages published to verdaccio was taking >5min, our longest running CI job. This was slow because we were starting up verdaccio, then publishing everything to it. I'm unsure exactly why that was sooo slow, but they haven't fixed it in the newer versions of verdaccio. It's predictable what the verdaccio database storage looks like though, so it's not that hard for an AI agent to script this. So that's what I've done. It's cut the run time of the CI job by about >50%, taking 2 min 30s.

We could push this further by sidestepping the yarn versioning step as well since that queries npm to see current versions, but theoretically we already know our version as it's stored in our package.json.

You can test that this verdaccio build isn't pulling from the latest on npm but rather the state of this branch by looking at ColorField in the test apps vs before the commit for handling the "Enter" key on main. On main, Enter does nothing, in this branch, it will commit the value, just like a NumberField.
