Minor here, you don't need to use sv.String() just using sv will get .String() called on it by %s.

I appreciate that it's not in this PR, but the kubernetesContraints looks overly broad, I am not sure that Flux supports those versions (and they're not supported upstream)?

The `--short` flag has been removed from `kubectl version` in 1.28 (https://github.com/kubernetes/kubernetes/blob/7fe31be11fbe9b44af262d5f5cffb1e73648aa96/CHANGELOG/CHANGELOG-1.28.md#L1718) so the command obviously fails now. This commit changes the behaviour of the `gitops check` command to create a client-go DiscoveryClient and use that to retrieve the server version. That way we don't have to rely on forking a `kubectl` process and the output being consistent. The code is now much cleaner, easier to read and properly tested. closes #4157 Signed-off-by: Max Jonas Werner <[email protected]>
The support policy of Weave GitOps is to "test Weave GitOps against the latest supported Kubernetes releases" which means that only 1.26, 1.27 and 1.28 are supported at this point. This change doesn't prevent Weave GitOps from being run on older versions of Kubernetes as the constraint is only used by the `gitops check` command which is purely informational.
