#985 Also allow Visual Studio 2026 to build from source

描述

I don't know where the info came from, This is either wrong or outdated:
https://github.com/Niko1221/Strata/blob/6f32ec070f23ced9f50e704d854d775da52591ab/setup.py#L992-L993

I just compiled strata with the following .bat script without any issues:
```batch
@echo off
call "C:\Program Files\Microsoft Visual Studio\18\Community\VC\Auxiliary\Build\vcvarsall.bat" x64 >nul
cmake -G Ninja -S . -B ./build ^
  -DCMAKE_BUILD_TYPE=Release ^
  -DSTRATA_ENABLE_CUDA=ON ^
  -DSTRATA_BUILD_TESTS=OFF ^
  -DCMAKE_CUDA_ARCHITECTURES=89 ^
  -DSTRATA_GGML_DIR=.\third_party\llama.cpp || exit /b 1
cmake --build ./build --target strata -j 8 && exit /b 0
echo   (the build stopped - trying it once more)
cmake --build ./build --target strata -j 8 || exit /b 1
```

As you can see I used Visual Studio 2026 (2026 = version 18)
Cuda version was:
```
