Remove Azure Static Web Apps workflows and CI configs

The `azure-staticwebapp.yml` and `static-web-app.yml` GitHub Actions workflow files were removed. These workflows previously handled the build and deployment of web applications to Azure Static Web Apps.

Additionally, a CI-specific `<PropertyGroup>` block was removed from `BlazorBootstrap.Demo.WebAssembly.csproj`. This block contained configurations to optimize the build process for CI environments, such as disabling AOT compilation and adjusting WebAssembly heap size.

These changes reflect a shift in the deployment or CI/CD strategy, potentially moving away from Azure Static Web Apps or adopting an alternative approach.
