Reorganize Blazor forms coverage 8.0

[guardrex]

I think what we eventually want to do here is build up the user's understanding of form handling in Blazor by building off of concepts they probably already know, like the basics of forms in HTML. So, I think that means the initially sections should start with just a plain <form> (not EditForm) and then build up from there. First show how you can handle the form submission from the server using @onsubmit. Then introduce EditForm as a more convenient way to build a server based form. Then introduce enhanced form handling from the server. Then introduce interactive form handling. But we don't have to do this restructuring right away. It can wait until we get the .NET 8 stuff covered.
