Improve CAPTCHA logic and update .NET SDK installer

Updated Survey.razor to ensure CAPTCHA runs only in browsers
by adding `OperatingSystem.IsBrowser()` to the condition.
Enhanced debugging in Survey.razor.cs with additional
Console.WriteLine statements for better logging of rendering
and data loading processes.

Replaced the .NET 9 SDK installer script with a new script
for installing the .NET 10 SDK, reflecting the latest version
and providing updated setup instructions.
