Documentation on creating Function app in Dedicated app service plan via Bicep is misleading

## Issue
In the docs regarding functions, infrastructure as code and specifically the part on creating a function app in a dedicated app service plan [Create a function app](https://learn.microsoft.com/en-us/azure/azure-functions/functions-infrastructure-as-code?tabs=bicep#create-a-function-app-2), the docs state that the variables WEBSITE_CONTENTAZUREFILECONNECTIONSTRING and WEBSITE_CONTENTSHARE are unsupported in this scenario.

However, function apps deployed without these variables set to correct values seem to be unable to start.
Errors detected is: 502 - Bad Gateway

When trying to access the app via Kudo:
```
Server Error in '/' Application
The user name or password is incorrect
```

## Mitigation
Re-deploying the function apps with correct values for these variables solved the issue.
