[bspeare]

How to test

1. Code review
2. Run through all the controls on http://localhost:6006/?path=/docs/components-cta--docs. Note, the inline version will only work with container queries. Move to item 4 for inline testing.
3. Test background colors use both the cta background color and the container background color and verify everything is visible.
4. Test container queries on "inline" version. Got to http://localhost:6006/?path=/story/components-cta--grid and change orientation to "inline" and test that it appears centered in three column grid. Remove "grid type" class and confirm that CTA appears inline.
