.NET: Added GettingStarted example demonstrating Dapr as an agent provider

[WhitWaldo]

Added example demonstrating creating an AIAgent using the Microsoft.AI.Extensions implementation of IChatClient using Dapr as the inference back-end provider pointing to Ollama in this example.

Motivation and Context

I'm the maintainer of the Dapr .NET SDK. In the last major release, I added a package to our SDK release to support IChatClient from Microsoft.Extensions.AI using Dapr's Conversation building block. As Microsoft only recently released this agentic framework, I was reading through the examples and saw a great opportunity to list the newly minted package as a sample agent implementation to the existing list.

Description

This doesn't change anything about the framework itself and only adds an agent provider to the existing list of samples. I've included a sample Dapr component file, provided instructions in the README at the project level explaining prerequisites and setup instructions and have otherwise minimized other changes (e.g. adding a line to the central package management under the appropriate section).

The other itself should otherwise be quite straightforward and keeping in line with the demonstration used in other similar samples.

@stephentoub @DeagleGross Can we get some eyes on this? Thanks!

Neat, I wasn't aware this existed.

I just added it in the last Dapr release - it wraps Dapr's Conversation building block.
