Badge color not responsive to dark theme.

[Zash]

The class used for Hats sets text color to white:

converse.js/src/shared/styles/badges.scss

Lines 34 to 35 in 12a7933

	.badge-secondary {
	color: white;

This leads to poor contrast when combined with a dark theme:

I imagine the solution is to use a variable, but which?

Probably just var(--background)

Thanks!
