[FEAT] Provide a link to the API documentation in the navbar

[tbouffard]

Is your feature request related to a problem? Please describe. Currently, there is only a link to the lib documentation. To go to the API documentation, users need to search in the page to find the link to the API documentation. Having a direct link to the API documentation in the example would highlight the API.

Describe the solution you'd like We could transform the Docs button, into a select box, as we do for the GitHub select.

Additional context To replicate in all pages 😿
