Adding this in combination with the localization provider will create a lanaguage version for all enabled languages that have no language version when publishing your translation.
Don't forget to add at least a Localization:AzureSubscriptionkey to the appsettings.json.
"Localization": {
"AzureSubscriptionKey": "Your Key",
"AzureEndpoint": "if different from the default",
"AzureRegion": "if you have set a specific region"
},
