The `SemanticKernelAgent` class has been updated to include an optional
`modelServiceId` parameter, allowing the specification of a service ID
for the model.
## Why are these changes needed?
Currently, `SemanticKernelAgent` uses the parameterless method for
resolving `IChatCompletionSerivce`. This will fail, when multiple models
are registered in the Kernel.
To support different models registered in the Kernel, I adopted the
resolving of the `IChatCompletionSerivce` within the
`SemanticKernelAgent` with an optional parameter. When it is not set, I
resolve the default instance, otherwise, I use the optional parameter as
a servide id for resolving the `IChatCompletionSerivce` service.
