Fix 02 readme -semantic kernel

[wtulloch]

The C# Semantic Kernel examples in the readme were invalid so have updated the base example and the plugin example.

Also removed the section on planners since planners have been deprecated in favour of auto invocation of functions.

The section on memory needs to be updated but still trying to find a good, simple example. :-)

• [nitpick] Verify whether importing native functions using both ImportPluginFromObject and ImportPluginFromType is intentional, as it may lead to redundant registrations.

kernel.ImportPluginFromType<NativeFunctions>();

[nitpick] Consider using a lowercase 'f' in 'focuses' for consistency with standard grammar.

	AutoGen is an open-source framework developed by Microsoft Research's AI Frontiers Lab. It Focuses on event-driven, distributed *agentic* applications, enabling multiple LLMs and SLMs, tools, and advanced multi-agent design patterns.

The array initialization syntax appears incorrect for C#. Consider using 'new[] { summarizeFunc }' instead of '[summarizeFunc]'.

Suggested change

	kernel.ImportPluginFromFunctions("SemanticFunctions", [summarizeFunc]);
	kernel.ImportPluginFromFunctions("SemanticFunctions", new[] { summarizeFunc });
