Remove reduntant method calling

[marcominerva]

Motivation and Context (Why the change? What's the scenario?)

In the following method:

kernel-memory/extensions/AzureQueues/DependencyInjection.cs

Lines 14 to 21 in 0d82c62

	public static IKernelMemoryBuilder WithAzureQueuesOrchestration(this IKernelMemoryBuilder builder, AzureQueuesConfig config)
	{
	config.Validate();
	builder.Services.AddAzureQueuesOrchestration(config);
	return builder;
	}
	}

There is a call to the AzureQueuesConfig.Validate method, but then the AddAzureQueuesOrchestration method is invoked, that in turns calls AzureQueuesConfig.Validate again:

kernel-memory/extensions/AzureQueues/DependencyInjection.cs

Line 27 in 0d82c62

config.Validate();

So, it is possible to safely remove the first invocation.
