Rewrites colored links again to use the color property instead of --bs-link-color-rgb value as nav links and more do not set or consume --bs-link-color-rgb. This could be an interesting change to tackle in v6, where components utilize more global CSS variable defaults, but not happening right now. This prevents a breaking change right now.
Also adds a new .link-body-emphasis helper—custom right now, not part of the loop, because we use the loop to turn static hex values into rgb values. With this new class, we don't want to use hex values, so we have to write something custom. Worth noting this could also be a change we make in v6—update $theme-colors to use CSS variables. Maybe, who knows.
