docs: <p>
  Creates a new version of the specified managed policy. To update a managed policy, you create a new policy
  version. A managed policy can have up to five versions. If the policy has five versions, you must delete an
  existing version using <a>DeletePolicyVersion</a> before you create a new version.
  </p>
  <p>
  Optionally, you can set the new version as the policy's default version. The default version is the version that
  is in effect for the IAM users, groups, and roles to which the policy is attached.

  Policies</a> in the <i>IAM User Guide</i>.
