[Bug]: Issue adding Stored Procedures (Azure Cosmos DB / NoSQL / GraphQL)

### What happened?

Following the instructions [here](https://learn.microsoft.com/en-us/azure/data-api-builder/views-and-stored-procedures#graphql-support-for-stored-procedures), we've run into issues registering a stored procedure with DAB.

Within Azure Cosmos DB, NoSQL, there's a container called "Persons"
Attached to the container is a Stored Process called "DefaultStoredProc"

We've the following command to register the Stored Proc:

```bash
dab add DefaultStoredProc --source Persons.DefaultStoredProc --source.type "stored-procedure" --source.params "searchType:s" --permissions "anonymous:execute" --rest.methods "get" --graphql.operation "query" -c "[locationOfConfigFile].json"
```

That command populates the config file with the below:
```json
"DefaultStoredProc": {
"source": {
"object": "Persons.DefaultStoredProc",
"type": "stored-procedure",
"parameters": {
"searchType": "s"
}
},
"graphql": {
"enabled": true,
"operation": "query",
"type": {
"singular": "DefaultStoredProc",
"plural": "DefaultStoredProcs"
}
},
"rest": {
"enabled": false,
"methods": [
"post"
]
},
"permissions": [
{
"role": "anonymous",
"actions": [
{
"action": "execute"
}
]
}
]
}
```

Nothing is created in the schema.gql file.

When we run this, using `dab start` (or `swa start`) we get the following error - `System.Collections.Generic.KeyNotFoundException: The given key 'DefaultStoredProc' was not present in the dictionary.`

Any and all advice greatly appreciated!

TY, Rich
