az webapp connection create sql fails on Azure Cloud Shell and requires odbc install

### Describe the bug

When trying to set up a connection from my Azure App Service to an SQL DB via the `Service Connector` the azure cloud shell command fails:

```text
az extension add --name serviceconnector-passwordless --upgrade
az webapp connection create sql --connection --source-id --target-id " --client-type dotnet --system-identity
The behavior of this command has been altered by the following extension: serviceconnector-passwordless
Checking if WebApp enables System Identity...
Connecting to database...
Please manually install odbc 17/18 for SQL server, reference: https://learn.microsoft.com/en-us/sql/connect/odbc/download-odbc-driver-for-sql-server/
```

this used to work before, and it is unclear on how to even install odbc for sql server on an Azure Cloud Shell.

### Related command
