Error in azurerm 3.0 upgrade guide

In the 3.0 upgrade guide of azurerm there is an error in the data source of azurerm_app_service.
The info says that azurerm_app_service is superseded by azurerm_linux_function_app and azurerm_windows_web_app, but azurerm_linux_function_app should have been azurerm_linux_web_app.
Do I need to only warn people here, or should I also make a ticket on github?
