Document Ambient Egress Gateways

[keithmattix]

Solo has a good blog post and @howardjohn discusses it in his personal blog, but we don't actually have any official istio docs showing how to do egress gateways with waypoints in ambient. This is a missed opportunity to show how much simpler ambient is in our official documentation

Hi @keithmattix , I’m interested in working on this issue. I’m new to Istio but willing to learn and contribute. Can I take this up?
