[Code Generation] add plop-scripts

[psimk]

@pota/plop-scripts

Commands

• plop - runs plop

Description

We have already been using a setup similar to this in most of our templates, for example the @pota/muban-template:

package.json

"scripts": { 
  "plop": "node --loader ts-node/esm ./scripts/plop.ts",
},

We are not going to be generalizing plop into a code-gen command as the plop templates and plopfiles are specific to plop itself, so if we ever want to switch to a different package, we would have to throw everything out and start from scratch.
