This pull request removes the
policy-controllerHelm chart (that leverages the fork of sigstore/policy-controller) and related documentation from the repository, updates installation instructions to reference the upstream Sigstore chart, and adjusts release and test workflows to reflect these changes. The primary focus is on deprecating the temporary fork and transitioning users to the official Sigstorepolicy-controllerchart.For the github provided trust-policies to work,
insecureIgnoreSCT: truemust be set. This was not necessary when using the GitHub fork of policy-controller due to it being set if using keyless directly in the policy-controller.
