Appends the version of the component into the build path

@yields Could you please review my change? I don't expect you to merge this into the main branch, but some feedback would be great!
I don't know of a `node/component` utility that can resolve the path to the local and get the `component.json` out of it. `builder.config.local` only gives me the name of the local dependency but not the path to the config I need.
