Feature: Add Numbered Icons to the Getting Started section

Adding numbered icons to the sidebar of the Introduction section could make it easier to understand the order to proceed in.

@yuval-hazaz, similarly to the sidebar labels PR, should we go ahead and close this one? What are your thoughts on implementing something similar to the image above with numbered icons? I feel this could be particularly useful in the introduction section.
