Emoji Picker should be able to take customization-color to have a correct background color

[J-Son89]

In the designs the emoji picker has a solid background color. Update the emoji picker to match these designs

Align with the design team on the expected behaviour.

Ensure this is not breaking the emoji picker for it's other uses on different pages
