Retrieves an asset by its ID and version number with OpenCloud auth.

Refer to the assetId endpoint for details on usage. This endpoint is expected to be called with API key authentication through apis.roblox.com/asset-delivery-api/v1/assetId/{assetId}/version/{versionNumber}. While you are able to make requests to this endpoint with Cookie authentication via assetdelivery.roblox.com/v1/openCloud/assetId/{assetId}/version/{versionNumber}, we highly discourage use this way. Expect unannounced removal of this second route in the future.
