Rename ubuntu to gnome and create a new ubuntu style.

Hi.

Ubuntu 20.04 uses Yaru as it's default theme where as GNOME uses Adwaita as it's default theme.

We can create a new ubuntu style that uses the Yaru theme and icons.

@ad1tyawagh would you be interested in working on this one?

Sure!

I will try to fix the color palette in that, and if it is satisfactory, I will do it for all the styles.

For that, I have translated the solarized color palette to the Xresources style using the nord theme as an example.
