chore: update lima example to use --with-terraform arg (#5655)

#5586 added the capability for install.sh to download and install Terraform automatically.
Using this now in the example Lima specification.
Also no longer hard-coding the instance name in favour of {{.Instance.Name}} in the output
that gets emitted upon successful instance provisioning.
