fix: Explictly specify microk8s.status output format

[TheRealChssAddct]

What does this PR do?

Explicitly specify microk8s.status output format (--format short) since microk8s recently changed the default format (with v 1.19.0), breaking the addons enabled preflight checks.

What issues does this PR fix or reference?

eclipse-che/che#16408

How to test this PR?

Using chectl with microk8s platform, where microk8s version is 1.19.0 or later, prior to fix, it will incorrectly fail on the MicroK8s preflight checklist, with the Error "The storage addon hasn't been enabled in microk8s".

After the fix, the preflight checks for storage and ingress addons enabled will succeed.

Hi @TheRealChssAddct. Thanks for your PR.

I'm waiting for a che-incubator member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
