fix: k3s yaml link so tutorial works and updated the image with new yaml url

[waltribeiro]

In preparation for my KCNA, I ran through Equinix's K3s and K8s tutorials. This React app was a big help, but it kept giving me a 404. So I updated the YAML and image.

Steps to Reproduce

1. Launch server with this user data:

#cloud-config

runcmd:
  - curl -sfL https://get.k3s.io | sh -
  - sleep 20
  - kubectl apply -f https://raw.githubusercontent.com/stevemar/react-wordle/main/reactle-kube-deploy.yaml

2. Received an error

3. Replace with this user data:

#cloud-config

runcmd:
  - curl -sfL https://get.k3s.io | sh -
  - sleep 20
  - kubectl apply -f https://raw.githubusercontent.com/stevemar/metal-code-snippets/main/yaml/reactle.yaml

4. Received working

5. Go to http://<localhost>:31000 and confirmed Reactle / Wordle app works.

fixes it not working, so lgtm. but in general, we should move away from the wordle clones to something like wordpress.

Should I create a new workshop for Wordpress using https://raw.githubusercontent.com/stevemar/metal-code-snippets/main/yaml/wordpress.yaml and then update the instructions for <ip>:30001 ?

@waltribeiro i would update this workshop with that link (provided it works!)
