  // Force the SDK to re-resolve credentials with the default provider chain.
  //
  // This action typically sets credentials in the environment via environment variables.
  // The SDK never refreshes those env-var-based credentials after initial load.
  // In case there were already env-var creds set in the actions environment when this action
  // loaded, this action needs to refresh the SDK creds after overwriting those environment variables.
  //
  // The credentials object needs to be entirely recreated (instead of simply refreshed),
  // because the credential object type could change when this action writes env var creds.
  // For example, the first load could return EC2 instance metadata credentials
  // in a self-hosted runner, and the second load could return environment credentials
  // from an assume-role call in this action.
