fix: fix calico manifests URL

[pmalek]

It seems that the old URL for calico manifests: https://projectcalico.docs.tigera.io/manifests/calico.yaml is not available anymore.

Calico docs explicitly mention a version in the URL so something like this has to be used: https://raw.githubusercontent.com/projectcalico/calico/v3.25.0/manifests/calico.yaml

Since these are in the repo and not attached to release artifacts we have to pick a tag or a branch. I reckon using master is not the best idea so let's stick to the latest version ATM.

Here's a CI run that has the error printed out: https://github.com/Kong/kubernetes-testing-framework/actions/runs/4144020162/jobs/7166576869
