Improve intro slides

[gcroci2]

• Update the slides in order to say less about Command, Chat, Autocomplete in the intro. Maybe remove part 2 slide
• Move context awarness slide to the introduction
• Highlight differences and common features among main tools, keep the table and the comparison, but slightly less detail
• Besides the areas of application, we got a comment about adding a framework/map/visualization to understand the capabilities of AI coder from small-scale tasks to large-scale tasks to their future capabilities.
• About the slide of “area of application”: one more item can be added: explaining errors/bugs

I updated the slides but I'm not sure about the comment about adding a framework/map/visualization to understand the capabilities of AI coder from small-scale tasks to large-scale tasks to their future capabilities. I made a slide but I don't like it that much, so I'm considering skipping it. I don't think it has a big added value
