Using a class property of type `Enum` triggers BC failure in CI workflow

Bug Report

I'm using the laminas/workflow-continuous-integration workflow and:

"backwardCompatibilityCheck": true

in .laminas-ci.json.

I have a class property of type (Backed)Enum:

class SomeClass
{
    protected VisibilityEnum $visibility = VisibilityEnum::Public;
}

that under the QA Checks (Backward Compatibility Check workflow triggers the error:

[BC] SKIPPED: An enum expression Namespace\VisibilityEnum::Public is not supported in class Namespace\Example in file /src/SomeClass.php (line xx)

I don't think this issue is pertinent to this CI action, but rather just the BC checker itself.
