Hosting models/render modes for 8.0

[guardrex]

This issue will track ...

• What we'll be doing with the Hosting models topic. Some options are ...
  • Keep it for <8.0 only with a new Render modes topic for >=8.0.
  • Keep it (with updates) SxS with a new Render modes topic for >=8.0.
  • Convert it in-place for all versions to a Render modes-focused topic and rename it (e.g., "Render modes" or "Hosting models and render modes").
• Across the Blazor docs, I hope 🤞🍀 we can swap client/client-side|server/server-side [rendering (SSR/CSR)] language for hosting model language without version flipping in most places. I hope it works to avoid a versioning 🎃 FrEaKsHoW 👹😨.
• In >=8.0 content, drop all references and examples for Blazor Server and hosted Blazor WASM projects.
