fix(storage-gcs): client uploads are enabled even if clientUploads is not set (#11527)

Client uploads were always enabled because a wrong variable was used,
when passing `enabled` to `initClientUploads`,
`gcsStorageOptions.enabled` instead of `gcsStorageOptions.clientUploads`

To enable client uploads with GCS you also additionally need to
configure CORS on Google Cloud, therefore this change breaks existing
logic
