Add magidoc documentation

[pelletier197]

Added magidoc documentation. See the example output here: https://pelletier197.github.io/countries

Once merged, the documentation will automatically be deployed at https://trevorblades.github.io/countries

To simplify my life, I needed to extract the schema in a separate file. This is easier to get the schema for me, and will be simpler for you to add the comments.

• For now, custom pages are empty. Only the generated documentation is shown. Feel free to add markdown pages if you want and move your examples in there. (See: https://magidoc.js.org/cli/magidoc-configuration#website)
• Documentation is rebuilt and deployed at every merge on the main branch.

Thank you!

Resolve #45

Looking great @pelletier197! 🎉 I tested out the site using magidoc preview and it works well.

I made a branch with a bunch of changes that make the linter happy again. Could you add me as a contributor to your fork, and then I can make a PR there?
