What steps did you take and what happened:
We get this error when using a private registry for policiesBundle, we have to use this because when pulling from ghcr.io we get the Rate Limit Error.

tls: failed to verify certificate: x509: certificate signed by unknown authority

Still when these setting is set:

policiesBundle:
    insecure: true

As Information the registry we want to pull from is without user+pw

Probably related to:
#2212
#2228

What did you expect to happen:

Not getting an Certificate Error when using

policiesBundle:
    insecure: true
