Stack Component Rendering Incorrectly

[rlpool06]

Describe the bug
The Stack component renders horizontally in production and vertically in local development.

To Reproduce
Steps to reproduce the behavior:

1. Create a Stack component with three divs inside. Styling props include mt={8} and gap="24px"
2. Check component in local development, should render as vertical
3. Check staging/production for same vertical orientation. Currently, it is rendering without the gap prop and is display: flex, causing it to be horizontal orientation.

Expected behavior
Expected behavior is the Stack component would be in a column with the gap prop applied.
