Context

Currently on the result page, the ecoIndex badge concept is explained with a couple of paragraphs, and the user can access to the GitHub page of the project if he wants to, and look for how to integrate the badge.

Objective

Improve the popularity of the ecoIndex badge by:

• Showing how to integrate it easily on the user's website by displaying an extract of code to copy/paste.

⚠️ The tricky thing is about the UI of such a widget, as the badge is available in 2 technical versions (with and without JavaScript) and 2 themes (light and dark), which leads to 4 possible combinations
