Add instructions for installing on Windows using cabal instead of stack

[vrom911]

Currently, I have only noticed Stack instructions. This could be optional, and users could choose for themselves, I guess.

@vrom911 I do not understand what you mean by only Stack instructions.

From what I recall all the Haskell Editor Setup instructions are using Cabal and Nix without any Stack.

For the Windows section, I see https://github.com/fairy-tale-agi-solutions/haskell-editor-setup#install-the-haskell-tool-stack , but not installation instructions for the Cabal tool.

@vrom911 Ah! I only used Stack instead of Cabal since I was looking at the easiest way of installing and Stack was recommended for HIE installation back then.
