Invalid Marshaling of ServerVulnerabilityProperties in SubAssessment

[bbernays]

Bug Report

The MarshalJSON() function for ServerVulnerabilityProperties the SDK is hardcoding the assessedResourceType as ServerVulnerabilityAssessment when in the sdk the const AssessedResourceTypeServerVulnerability has a value of ServerVulnerability

This means the following code will never return true:

func isTypeServerVulnerability(assessment *armsecurity.SubAssessment) bool {
    additionalType := assessment.Properties.AdditionalData.GetAdditionalData()
    return additionalType.AssessedResourceType == armsecurity.AssessedResourceTypeServerVulnerability
}

This value is also used in this function and will have to be changed as well
