Refactor FilterAreaActions to have consistent spacing across all browsers

[solkaz]

Description

Sets the justify-content CSS property to space-around to make the spacing for the buttons consistent across all browsers

Motivation and Context

Previously, we were setting the justify-content property to space-evenly, which is supported by Firefox, but not Chrome or Safari, so there would be an inconsistency in how the buttons are placed.
