    docs: Add .editorconfig file
    
    This should ensure that all editors which support
    https://editorconfig.org/ use 2-space indentation with spaces (not tabs)
    by default.
    
    This isn’t a full specification of the GLib coding style (see
    https://gitlab.gnome.org/GNOME/gtk/blob/HEAD/docs/CODING-STYLE.md for
    that), but is a correct subset of it.
