.Net: Bug: Sample code in GitHubPlugin.cs is not correct

[svandenhoven]

Describe the bug
I am following the guidance in https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/examples/example-chat-agent?pivots=programming-language-csharp. This refers to https://github.com/microsoft/semantic-kernel/blob/08a41117c24cdd1f8f98332a222abc5b8f46ea0d/dotnet/samples/LearnResources/Plugins/GitHub/GitHubPlugin.cs as GitHubPlugin for the sample agent.
In line

semantic-kernel/dotnet/samples/LearnResources/Plugins/GitHub/GitHubPlugin.cs

Line 102 in 08a4111

HttpResponseMessage response = await client.GetAsync(new Uri(path));

there is code line:

HttpResponseMessage response = await client.GetAsync(new Uri(path));

This gives the error:

An exception of type 'System.UriFormatException' occurred in System.Private.CoreLib.dll but was not handled in user code: 'Invalid URI: The format of the URI could not be determined.'

This is because the path has value ("/user") and this is indeed an invalid URI.

This can be solved by changing the line to

HttpResponseMessage response = await client.GetAsync(path);

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/examples/example-chat-agent?pivots=programming-language-csharp
2. Follow the whole guidance
3. Build and run the application and use message "What is my username?"
4. See error

Expected behavior
A clear and concise description of what you expected to happen.
The GET on the GitHub should be executed and the agent should answer with the username.
