DevToolsProtocolExtension's Network.Headers type is wrongly defined

Description
The Headers class defined under Microsoft.Web.WebView2.Core.DevToolsProtocolExtension namespace's Network class is defined as an empty class with no properties or methods. This makes it impossible to retrieve the actual header data after retrieving data about a request or response.

This is the definition of a Response class, for example:

Here you can see that Headers class has no methods or properties whatsoever, making it impossible to retrieve data from it:

From the Chrome Devtools' GitHub page documentation:

Network.Headers - Request / response headers as keys / values of JSON object. Type: object

You can see that the headers property indeed is an object containing key-value pairs of headers (Taken from protocol monitor):

I'm assuming this happened because the types are auto-generated from some other source - perhaps the header property should instead be defined as something like Dictionary<string, string> or some sort of collection containing key-value pairs?

If the types are auto-generated, it also might be worth it to verify other auto-generated types to see if any of it also has no properties / methods?

Start at the Microsoft.Web.WebView2.Core.DevToolsProtocolExtension.Network.Headers definition and compare it with the Chrome DevTools Protocol Network.Headers documentation linked in the issue. Trace how it is exposed through request and response data; done means callers can retrieve header names and values rather than receiving an empty type.
