The host-gateway configuration is specific to Docker Desktop (but doesn't break Podman)

Where: search for host-gateway

https://github.com/search?q=repo%3Arestatedev%2Fdocs-restate%20host-gateway&type=code

For example:

https://docs.restate.dev/server/deploy/docker

Notes for documentation:

• The host-gateway value is a Docker Desktop thing
• Moby, Rancher Desktop w/Moby and Podman already have host.docker.internal mapped; there is no need for host-gateway
• Podman is not broken by the unnecessary --add-host=host.docker.internal:host-gateway
• Rancher Desktop is broken by --add-host=host.docker.internal:host-gateway because host-gateway is undefined

Aside: On current versions of Rancher Desktop port 9080 may already be used for its dashboard, but this will change when this fix is released.
