Broken on Windows systems

I love the idea of this plugin and tried it just now but sadly ran into an error where it tries to create the plugin file for the UNIX config path of nvim, which results in the folder `[...]\AppData\Local\nvim\nil\.local\share\nvim\lazy\{plugin-name}` being created, where it should be `[...]\AppData\Local\nvim\lua\plugin\{plugin-name}`. I only recently started using nvim so i apologize for not being able to open a PR for this, since my Lua code probably is absolute garbage.
