New code editor & New API docs

Our code editor needed some improvements in regards to UX and UI.

It's now faster, more integrated to the platform, and provides easier ways to add and edit code samples.

Our API docs also needed some 😍

Now it's much faster & intuitive, and it uses the same code editor for the code samples. And it nicely shows in the table of content.

Happy documenting from the Archbee team!
