Diagrid dashboard run command in docs panics on Linux

[irbekrm]

Describe the issue
When I follow the steps in getting started guide on a Linux machine and run docker run -p 8080:8080 ghcr.io/diagridio/diagrid-dashboard:latest it panics:

$ docker run -p 8080:8080 ghcr.io/diagridio/diagrid-dashboard:latest
time="2026-04-02T07:39:53.048040523Z" level=info msg="Can not load statestore from localhost, trying docker internal network" instance=acd7d08d96a8 scope=diagrid.dashboard.statestore type=log ver=unknown
panic: redis store: error connecting to redis at host.docker.internal:6379: dial tcp: lookup host.docker.internal on 192.168.1.254:53: no such host

goroutine 1 [running]:
github.com/diagridio/diagrid-dashboard/cmd.Run()
        /app/cmd/app.go:24 +0x4b4
main.main()
        /app/main.go:6 +0xf

Seems like the dashboard tries to connect to Redis on host using host.docker.internal DNS name, but this only resolves on Mac/Windows, not Linux.

Expected content
On Linux run:

docker run --add-host=host.docker.internal:host-gateway -p 8080:8080 ghcr.io/diagridio/diagrid-dashboard:latest

(this works as expected)
