Quickstart issue - example not available at http://localhost:3000

# The issue:

I am following the tutorial here: [https://skaffold.dev/docs/quickstart/](url)
After fixing the issues with getting `skaffold dev` to run** and then running `minikube tunnel -p custom` in another terminal there is nothing at http://localhost:3000 (thee target site for the example app).

# The solution:

- run: `kubectl get service web` and manually construct the url from EXTERNAL-IP and the port; OR
- run: `minikube service web --url -p custom` where this is done automatically; OR
- run: `minikube service web -p custom` where it is done automatically and the default browser is opened at the url

Docs should be updated to reflect both issues (or at least these workarounds if they work in some other setups).

# My setup:
- OS: Ubuntu 24.04 (Noble)
- minkube: v1.36.0
- kubectl: v1.33.3
- skaffold: v2.16.1

** Mentioned in #9712. The workaround is to add `trustBuilder: true` to the skaffold.yaml.
