RFC: Move add-ons templates on template's packages to cli-tool package

[hoangmirs]

Issue

• We created a CLI to generate a React project. So now, our template is able to support generating multiple React templates e.g. CRA, Vite, NextJS, RemixJS
• But now, we are putting the add-ons logic into cli-tool package and add-ons templates (base code, config files) into each template package.
• It might be better if we move add-ons templates to cli-tool package, the folder could be packages/cli-tool/template/addons. Then we just need to copy from here to the generated project. Make sure that the generated project has a common folder structure.
• We can test each addon by generating a simple project and checking if it can be installed on the generated project.

What's next?

If you agree with this, then we might:

1. Create templates that have the similar folder structure
2. Use CLI to generate a project with option: --template=cra, --template=nextjs, --template=vite
3. Use CLI to install add-ons: install NPM package, copy files
4. Add a postProcess function to fix linter, commit, ...

The the "CLI to install add-ons", I think we do not need to publish an NPM package, we can directly CURL the add-ons folder and extract it :D

I'm doing that to download the vite template :) The nice thing is that then we can test on a specific branch (just need to push the branch changes first).
