Optimize .NET SDK setup and Azure SWA deployment

Replaced `actions/setup-dotnet` with a custom caching and
installation process for the .NET 10 SDK to improve build
efficiency. Added caching using `actions/cache` and a
custom installation script. Updated environment variables
and added a verification step for the .NET installation.

Simplified Azure Static Web Apps deployment configuration
by removing redundant comments and unused parameters.
Updated `app_location` to point to
`BlazorBootstrap.Demo.WebAssembly` and retained necessary
build and output configurations. Cleaned up unused
repository/build configuration examples for clarity.
