WIP: changing civo gitlab stack from talos to k3s

testing k3s distro in civo after changes

@johndietz Is CIVO's Kubernetes offering now based on K3s as opposed to Talos Linux or does it plan to migrate to the former?

I'm asking because as this comment states, #2087 might be a blocker.

[2023-05-06] For reference:

Here at Civo, we have introduced the use of Talos Linux for our tenant clusters. This decision was made due to Talos Linux providing a more robust and customizable platform with advanced security features that allow for specialized use cases and strong security measures out of the box.
