Reframe HTTP lesson (#7032)

@parlough - You were so right about the async and http pages
overlapping. The HTTP part of async is the most basic possible http
request and really there for a "quick win", while the http lesson goes
deeper. So I reframed the intro of http.md to be more clear about the
difference. WDYT?

+In Chapter 3, you used the `http` package to make a simple request. Now, you'll

 :::secondary What you'll learn
 
-*   Construct `Uri` objects for API requests.
-*   Make HTTP GET requests using the `http` package.
-*   Handle API responses and decode JSON data.
+*   Construct complex `Uri` objects with query parameters.
+*   Apply HTTP requests within a structured package architecture.
+*   Map JSON responses to the data models created in Chapter 9.
 *   Export functions and models from a Dart library.
