dev: Fix kube-linter github workflow

[somaritane]

Currently k8gb kube-linter produces results that are not on par with local kube-linter command execution:

Warning: failed to load object from chart/k8gb: failed to render: template: k8gb/templates/operator.yaml:102:19: executing "k8gb/templates/operator.yaml" at <eq "LoadBalancer" (.Values.coredns.serviceType)>: error calling eq: incompatible types for comparison
Warning: no valid objects found.

Warning: failed to load object from chart/k8gb/templates/external-dns/rbac.yaml: failed to decode: Object 'Kind' is missing in '---'

It should be corrected so that:

• it uses a recent version of kube-linter-action (1.0.4)
• it points to the correct chart repository (chart\k8gb)
• it generates an output format that can be visualized by GitHub (sarif?)
• it uses .kube-linter.yaml config format for both local and GH workflow experience

Looks like it's premature to use .kube-linter.yaml yet as there's no exclusion/inclusion filters for files available, and we (luckily) don't need to disable particular kube-linter checks.
