Make an image with kube-linter to make CI/CD faster

[nikhars]

A large part of CI today is spent on installing kube-linter in the GHA. We could optimize this step and reduce CI/CD close to a minute by using a pre-built image which already has kube-linter installed. The breakdown of CI time is shown in the attached image.

You could try installing the binary from release rather than using go install first, that would probably cut it down to a few seconds without having to manage a docker build chain.
