feat(snippet): update llama.cpp snippet to include windows

[mfuntowicz]

This PR adds the Windows way of installing and running llama.cpp on such OSes.

llama.cpp is now available on WinGet and as easy installable as brew on Windows machines now.

PS C:\Users\momo-> winget install llama.cpp
PS C:\Users\momo-> # Load and run the model:

we could even make those options dependent on navigator.userAgent.includes("Windows") (when it's run in frontend code)

cc @gary149 on whether we want to do it or not.

In any case this can be in a later PR
