test(azure): include ServiceNoSQL in GetServiceClient test matrix

The table-driven test TestAzureProvider_GetServiceClient_AllServiceTypes
was missing common.ServiceNoSQL, leaving the GetServiceClient NoSQL
routing branch uncovered. Add {common.ServiceNoSQL} to testCases so
NewCosmosDBClient construction is verified alongside other service types.

Fixes CodeRabbit finding on PR #560.
