feat: Allow images to be zoomed in in docs for better visualization of it

[erickzanardo]

Description

We have some images in the docs which serves as support for what is being documented. But some of them are too small, or they have too many details (like a screenshot) to be readable.

The codemagic screenshot in this page is a good example.

We could make a zoom button that would open the image in a modal or something like that, allow the user to focus on the image and be able to better "read" it.

Requirements

• Implement a way to be able to zoom/focus an image in the docs.
