Add light version

[FineFindus]

Thanks for creating this theme. As someone who sometimes prefers to use light mode, it would be great if this theme also offered a light version, similar to the nordtheme website itself.

It's a great idea but I think it's a big work as I think it will be necessary to redefine all highlights.
I will make some tests
