create option to use Windows openssh executables instead of NixOS ssh

Problem

When using keepassxc to manage ssh keys from windows site, there are multiple ways to make them available inside WSL.

Solution

One is to simply use the windows binaries.

• See SSH Agent support for WSL  keepassxreboot/keepassxc#9585 (comment) for inspiration
• essentialy, the ssh and ssh-add and probably other executables would need to be symlinked to the windows ones

This is similar to how the windows docker-for-desktop gets integrated into wsl, and vscode. It would be awesome if nixos-wsl supports this case optionally.

You can already just use ssh.exe and ssh-add.exe like how in the comment you linked.

[schlichtanders]

Yeah, that is awesome. It would be great if everything using ssh, like git, would work immediately by activating a wsl configuration

[SuperSandro2000]

You can easily do that by replacing the ssh in your path with a symlink to ssh.exe. I do not think that doing that globally is a good idea as windows ssh usually lacks a bit behind, might be missing patches and debugging such setups is generally a lot harder. To make it short, I don't think we should add such an option.

Thanks for evaluating 👍
