build: offload package.json scripts to ts-node scripts

I don't mind the `dep:` scripts, but the others are currently getting out of hand...

I just need these scripts:
- dev
- dev:docs
- publish

And all other things that happen should happen in a ts-node script inside `scripts/`, using the dependency `fs-extra` as much as possible.

Also:
Anything that happens in the `prepare` script should be automated with a watcher somehow:
- whenever anything in `/packages/form` changes, run something similar to the currently set up `prepare:form`
- whenever anything in `/packages/table` changes, run something similar to the currently set up `prepare:table`
- whenever anything in `/packages/utils` changes, execute `npm run build` in that folder

The scripts in package.json shown below should therefore be reduced to just the 3 I mention above.
