Regex to determine path delimiters

Fix for #611

Hasn't been tested on Linux, and you might know a better way to fix it.

Thank you for the PR :) I think this is a good approach! there might be some things that we can do to integrate it more tightly into the codebase. Let me know what your thoughts are on the following:

1. Neovim 0.8 introduced vim.fs.normalize(), which converts allows for unifying the representation of paths across operating systems.
   • We have used vim.fs.normalize() in other parts of the code
2. We have a dedicated fs module filled with filesystem helpers
   • we could implement a fs.split_path based on whether vim.fs.normalize() is available
3. Then, we can replace instances of splitting filenames over path separators with fs.split

Yes, agree, this would be a great solution.

Are you interested in taking a stab at it? I'd be happy to answer any questions

I'd glad to help, but right now I don't have enough time to dive into all of this, since I only recently jumped into the Neovim and Lua :)

That's fair 🙂

I appreciate your time digging into the root cause of the issue; it will make enacting these changes significantly easier!
