Update MVC tutorial series for .NET 10 and Visual Studio 2026

[Copilot]

Updates the 10-part "Get started with ASP.NET Core MVC" tutorial series to support .NET 10 and Visual Studio 2026.

Changes

• Moniker ranges: Added >= aspnetcore-10.0 sections to all 10 tutorial parts
• Metadata: Updated ms.date to 01/22/2026, changed prerequisite includes to reference .NET 10 files
• Include files: Created version-specific includes:
  • start-mvc/includes/start-mvc9.md for .NET 9 legacy content
  • RP-MVC/validation-net10.md for validation rules
  • add-EF-NuGet-SQLite-CLI-10.md for Entity Framework CLI commands
• Screenshot structure: Created _static/10/ folders for all parts with v9 screenshots as placeholders (43 files)

Pattern

Follows PR #36590 structure for Razor Pages .NET 10 updates:

• Latest version content in main moniker range
• Older versions moved to include files
• Screenshot paths reference version-specific folders

Known Limitations

• Screenshots in _static/10/ are copied from v9 and require replacement with actual VS 2026 captures
• Sample code references remain on MvcMovie90 folders (no behavioral changes between .NET 9/10)
