[AWS][Security Hub] Update Donut charts with Pie

[kush-elastic]

• Enhancement

What does this PR do?

• In general pie/donut charts are not recommended for visualizing any data. Other options would be to use treemap instead where it's much easier to notice the real proportions of data. Or even instead of a donut, a pie chart can be used because there's more space for labels.
• We have migrated AWS Security Hub Summary dashboard to use Pie Charts.

Checklist

LGTM!

Approval as codeowner.

On the basis that there is more room for labels in the pie chart this is a tenuous improvement, weighed against studies that have shown doughnut charts are marginally less deceptive than pie charts (as noted, neither should be used since humans are terrible at both angle comparison and relative areal assessment).

Ideally, we'd use something else.
