SDK is generated by GitHub agent workflow

Generate SDK for the TypeSpec project and update the generated SDK details in the release plan using release plan work item. Generate a summary and update it back in the linked GitHub issue once SDK pull requests are generated.

Start with the TypeSpec project at specification/containerservice/resource-manager/Microsoft.ContainerService/fleet/ and inspect the linked API specification pull request. Use the GitHub agent workflow to generate the JavaScript, Go, Python, .NET, and Java SDKs. Done means the generated SDK pull requests exist, a summary is posted here, and the release plan work item is updated without releasing the SDK.
