GraphQL–Application Insights integration for HotChocolate 13

If you are a regular reader of my blog, you've certainly seen my earlier post on how to integrate Application Insights telemetry in your HotChocolate based GraphQL backend.

IMPORTANT: Although the code below will still work, I would recommend to switch to the integrated OpenTelemetry functionality and send the information to Application Insights in this way.
