[RFE] Add Use Case section to the IG website

[mayasingh17]

Current situation

Currently, we have some use cases in the demos of the gadgets in the documentation section of the Website however, I think they should be front and center - more prominent like Cilium does on their website: I really like how Cilium does it here: Cilium - Cloud Native, eBPF-based Networking, Observability, and Security

Impact

With use cases added to the website users will be able to easily understand how they can use the gadgets of IG in real life

Ideal future situation

After the implementation we will have more engagement with the website and more users of gadgets

Implementation options

As shown on the Cilium website, we can have sections for different categories of use cases and then tiles for each specific use case (maybe the gadget name as a subtitle on the tile) and then you can click on the use case tile and it will link to a page describing how to use gadgets to achieve what is needed for that use case
