Add specifics for how to configure garbage collection settings in ASP.NET framework web apps

### Type of issue

Missing information

### Description

It is my understanding that ASP.NET web apps have different ways that garbage collector settings can be configured. You can configure them machine-wide in the global aspnet.config file or per-app-pool.

This documentation page should have a section that covers the various ways you can configure GC settings for an ASP.NET framework web app in IIS.
