feat: create Vue-CLI dev project

Goal:

- we need to check if Planetar is usable with Vue CLI projects that don't have Quasar (currently it might still cause issues)
- we need to find out WHAT the issues are IF there are any -- and fix them as well
- eventually we might add some link to this Vue-CLI project to show how it can be set up

Steps:

- [ ] Create a new folder called `dev-vue-cli` in `packages` in which you create a new empty project with Vue CLI.

- [ ] Make sure the package.json is set to `"private": true` like the `packages/dev` project. (this prevents lerna from trying to publish this to NPM)

- [ ] Copy 3 simple Vue components from the `packages/atoms` folder into this Vue CLI project inside a folder called "components"

- [ ] `lerna add planetar --scope dev-vue-cli`

- [ ] Look at the `packages/dev` folder to see how Planetar is set up, and do the same for Vue CLI.
- try to do the same as `packages/dev/src/pages/component-gallery/PageComponentGallery.vue`
- don't forget to do:
```
import Planetar from 'planetar'
Vue.use(Planetar)
```
