Provider documentation is out of date

[AlexPSplunk]

Documentation for resource victorops_escalation_policy is out of date. Current documentation (in GitHub and on Terraform) only shows 2 possible values for victorops_escalation_policy.step.entries[].type (rotationalGroup, targetPolicy):

step {
        timeout = [time-out duration in seconds]
        entries = [
            {
                type = [ rotationalGroup | targetPolicy ]
                slug = [ rotatioGroup slug | next escalation policy ID ]
            },
        ]
    }

Code in github indicates that there are 7 values accepted here: "user", "email", "rotationGroup", "rotationGroupNext", "rotationGroupPrevious", "webhook", "targetPolicy".
