Pepr policies do not trigger if allowPrivilegeEscalation is null

[JaseKoonce]

Environment

Kubernetes distro being used: EKS

Steps to reproduce

1. Without any Exemptions create a pod without setting allowPrivilegeEscalation.

Expected result

allowPrivilegeEscalation defaults to true when not set, so I would expect to be unable to apply the manifest file.

Actual Result

You are allowed to apply the manifest files without Pepr triggering.

Visual Proof (screenshots, videos, text, etc)

Severity/Priority

Medium

Additional Context

Issue is caused by the filtering allowing both undefined and false, when it should only allow false for allowPrivilegeEscalation.
