      * Previously, the installation program required a non-existent permission `s3:HeadBucket` when installing a cluster on AWS. With this update, the installation program correctly requires the permission `s3:ListBucket` instead. (link:https://issues.redhat.com/browse/OCPBUGS-31813[*OCPBUGS-31813*])

      Description of problem:

          Installer requires the `s3:HeadBucket` even though such permission does not exist. The correct permission for the `HeadBucket` action 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. Install a cluster using a role with limited permissions
    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

      Expected results:

          Installer should check only for s3:ListBucket
