      * Previously, the Cloud Credential Operator (CCO) checked for a non-existent `s3:HeadBucket` permission during the validation checks in mint mode that resulted in a failed cluster installation. With this release, CCO removes the validation check for this non-existing permission so that valdiation checks pass in mint mode and the cluster installation does not fail.

      This is a clone of issue OCPBUGS-31678. The following is the description of the original issue:
      —
      Description of problem:

          The code requires the `s3:HeadObject` permission (https://github.com/openshift/cloud-credential-operator/blob/master/pkg/aws/utils.go#L57) but it doesn't exist. The AWS docs say the permission needed is `s3:ListBucket`: https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadBucket.html

      Version-Release number of selected component (if applicable):

          4.16

      How reproducible:

          always

      Steps to Reproduce:

          1. Try to install cluster with minimal permissions without s3:HeadBucket
    2.
    3.

      Actual results:

      level=warning msg=Action not allowed with tested creds action=iam:DeleteUserPolicy
level=warning msg=Tested creds not able to perform all requested actions
level=warning msg=Action not allowed with tested creds action=s3:HeadBucket
level=warning msg=Tested creds not able to perform all requested actions
level=fatal msg=failed to fetch Cluster: failed to fetch dependency of "Cluster": failed to generate asset "Platform Permissions Check": validate AWS credentials: AWS credentials cannot be used to either create new creds or use as-is
Installer exit with code 1

      Expected results:

          Only `s3:ListBucket` should be checked.
