fix: solve error check k8s workflow main

[marbonilla]

Description

This PR include a fix to the Check k8s manifests workflow to resolve the error:

invalid value "latest" for flag -kubernetes-version: latest is not a valid version. Valid values are "master" (default) or full version x.y.z (e.g. "1.27.2")

[Ian2012]

@marbonilla remember to run the workflow on pushes to main

on:
    push:
       branches: main

@marbonilla @Ian2012 Why did it work in previous builds?

[MoisesGSalas]

@jfavellar90 I'm guessing that it might be because the utilities used for testing aren't pinned (

drydock/.github/workflows/kubeconform-validation.yml

Line 44 in c695294

kubeconform: latest

) and a new release of kubeconform broke the thing.

[jfavellar90]

I would suggest a couple of things here:

• Could we add a step in the validation job to print the version of Kubernetes, Kustomize, and Kubeconform we are running the tests against? This can help to debug when the action fails.
• Could we pin the Kubeconform version? The latest one is v0.6.6. We can update the version in the action every time we release the version compatible with the new Tutor version.

I'm fine with that approach
