feat(themes): jump-label for modus themes (#10538)

Add styling for jump-labels for modus themes. I couldn't find
any official approach here so picking `yello-cooler`. `cooler` is
used for other meta highlights by modus and yellow seems to be
used the least - only warnings, so there's little chance of colliding
with other highlights.
