Update Blazor Hybrid template to match new Blazor Web App conventions

[danroth27]

We've made a number of changes to the content in the new Blazor Web App template to clean things up:

• New Components folder
• Cleaned up names and content for the Home, Counter, and Weather pages
• New Include sample pages option

We should update the .NET MAUI Blazor Hybrid template to match these changes.
