Update Swashbuckle packages and improve parameter matching

Updated `MinimalSample.csproj` to change `Swashbuckle.AspNetCore`
version from `6.8.0` to `6.8.1`. Similarly, updated
`MinimalHelpers.OpenApi.csproj` to change `Swashbuckle.AspNetCore.SwaggerGen`
version from `6.8.0` to `6.8.1`. Modified `GetByName` extension method
in `SwaggerExtensions.cs` to use case-insensitive comparison for
parameter names with `StringComparison.OrdinalIgnoreCase`.
