Fix badge pill border radius to avoid clipping

What does this MR do and why?

This MR moves away from badge pill since they had two issues when used for feature flag strategies

• they were in general not a good fit to convey the data, badge pills are usually used to show smaller sets of data mostly meta data
• with many environments the text would clip out of the badge pill (see screenshot)
