ggplot gallery: Donut chart edits

[OskaratOmni]

Reviewer comments:

• We typically don’t use donut charts with more than 2 options because it’s hard for people to decipher. When we do use donuts, the whole is usually smaller (50% in excel) and try to have the description next to the piece of the donut it’s referring to

I think there's an example of a donut in the templates we sent earlier.
