// Deletes the specified managed policy.
//
// Before you can delete a managed policy, you must first detach the policy from
// all users, groups, and roles that it is attached to. In addition, you must
// delete all the policy's versions. The following steps describe the process for
// deleting a managed policy:
//
//   - Detach the policy from all users, groups, and roles that the policy is
//     attached to, using [DetachUserPolicy], [DetachGroupPolicy], or [DetachRolePolicy]. To list all the users, groups, and roles that a
//     policy is attached to, use [ListEntitiesForPolicy].
//
//   - Delete all versions of the policy using [DeletePolicyVersion]. To list the policy's versions,
//     use [ListPolicyVersions]. You cannot use [DeletePolicyVersion]to delete the version that is marked as the default
//     version. You delete the policy's default version in the next step of the
//     process.
//
//   - Delete the policy (this automatically deletes the policy's default version)
//     using this operation.
//
// For information about managed policies, see [Managed policies and inline policies] in the IAM User Guide.
