K8SPG-777 set crVersion

[nmarukovich]

CHANGE DESCRIPTION

Problem:
Add validation for crVersion and ensure it is set if empty.
Since crVersion is defined as a string, we must store it as a string value to avoid validation errors.

// Version is the application version in the format X.Y.Z (e.g., "2.7.0").
	// +kubebuilder:validation:Pattern=`^$|^\d+\.\d+\.\d+$`
	// +kubebuilder:example="2.7.0"
	CRVersion string `json:"crVersion,omitempty"`

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:
Short explanation of the solution we are providing with this PR.

I think the importing order here is wrong as correctly the linter complains. Also the alias for the import is not needed at all. We can drop it.
