as you post here, I suppose you have internet access
if your browser connected to the ESP32 does not have internet access, then you need to replace that request by a local request (possibly served by your ESP32. it's a ~30KB file)
If you have internet access but can’t click that link and get the file then it means that for whatever reason Google decided that this resource is not available for you where you live.
Then no one should break the reason for making this unavailable
