Before this commit, im status icon for "away" was brown
in white mode.
This comes from MILK redesign change changes the color of
`text-warning`, from yellow to brown in white mode.
This commit fixes the issue by explicitly using yellow color,
regardless of theme. Dark mode kept the yellow color, so this
is unchanged.
