K3  Provisioning commands

While running the Pre-reqs on the workshop I noticed that k3 spin up command failed,  it should be the below as per the change in k3d version 5.2.2

```
k3d cluster create workshop \  
--k3s-arg "--disable=traefik@server:0" \
-p "80:80@loadbalancer" \
-p "443:443@loadbalancer" \
--agents 2
```
Change is on second line. I can raise a PR if the issue is accepted.
