Subject: [PATCH] Add conditional MapOpenApi for .NET 9.0 or newer

Introduced a preprocessor directive `#if NET9_0_OR_GREATER` to conditionally include the `app.MapOpenApi();` method call. This ensures that the `MapOpenApi` functionality is only executed when the application targets .NET 9.0 or later, maintaining compatibility with earlier .NET versions.
