Fixe invalid kubebuilder marker, that makes pinned plural name does not work.

[RainbowMango]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

When configuring CRD naming and scope the valid marker should be the format +kubebuilder:resource:xxx, but the operator mistakenly marked +kubebuilder:xxx, which makes the mark doesn't work.

Which issue(s) this PR fixes: Fixes #

Special notes for your reviewer:

I found this during updating the controller-tools to v0.12.0+, and I found the plural name of Operator changed to Karmada instead of Karmadas. That means the pinned plural name not work.

Does this PR introduce a user-facing change?:

NONE
