CLI: Display basic tips and information after creating a project or package

Description

I think it would be really helpful to display to the user a sort of “next steps” in the CLI after having run frontity create or frontity create-package !

Currently this is the output for running frontity create-package lalala :

> ~/Testing  npx frontity create frontity-hello-test
npx: installed 147 in 30.758s
✔ Ensuring /Users/czapla/Testing/frontity-hello-test directory.
✔ Creating package.json.
✔ Creating frontity.settings.js.
✔ Cloning @frontity/mars-theme.
✔ Installing dependencies.
✔ Downloading favicon.ico.

Frontity project created.

? Do you want to receive framework updates by email? No

Ok, that's fine! 😉
You can subscribe at any point with npx frontity subscribe <email>.

Run cd frontity-hello-test && npx frontity dev and have fun! 🎉

You can find docs at https://docs.frontity.org/.

We can add something like:

Your theme is in `frontity-hello-test/packages/mars-theme`. 

To learn why frontity projects are divided into packages: https://docs.frontity.org/learning-frontity/packages.

Now: 
1. Edit the `settings.frontity.js` to:
  - Point your theme to your REST API endpoint
  - Add a name and description to your site
Learn more: https://docs.frontity.org/learning-frontity/settings

2. Look in the `frontity-hello-test/packages/mars-theme/src/index.js to:
  - Add custom settings to your theme
  - Add state https://docs.frontity.org/learning-frontity/state
  - Add custom actions https://docs.frontity.org/learning-frontity/state

This is super basic, just to give an idea.
