az load test app-component add does not work for Microsoft.Sql/servers/databases

### Describe the bug

When trying to add a SQL database to a load test server-side components via the Azure CLI Load Test extension, the following error is emitted: `cli.azure.cli.core.azclierror: Type of app-component-id and app-component-type mismatch: microsoft.sql/servers vs Microsoft.Sql/servers/databases`

When troubleshooting the issue, it looks like the problem is in this code:
[extensions/blob/8f63159b283c74c20d642b3c1c271090447bc2de/src/load/azext_load/data_plane/utils/validators.py#L155)](https://github.com/Azure/azure-cli-extensions/blob/8f63159b283c74c20d642b3c1c271090447bc2de/src/load/azext_load/data_plane/utils/validators.py#L155)

Specifically this line: `provider_name = "/".join(namespace.app_component_id.split("/")[6:8]).casefold()`

Since the full type of the database is not included in this split.
