Message:

Twenty Twenty: Avoid PHP warnings in 8.1 due to incorrect usage of wp_add_inline_style().

This changeset adjusts the logic to use a more defensive approach, to avoid passing potentially invalid values to wp_add_inline_style().

Props flixos90, mukesh27, costdev, swissspidy, poena, sabernhardt.
Fixes #57777.
