Active tab appearance KO in Nav light

[pismy]

• Operating system and version: any
• Browser and version: any
• Reproduced on: Boosted 4.3.1
• Component: Nav light
• Description: Using a Nav light, the appearance of a tab doesn't change when selected
• Cause: jQuery script makes use of the active CSS class while selecting a tab while Boosted implements an o-active CSS class
• Workaround: duplicate the Boosted o-active class in a active selector:

.o-nav-light .active {
    color: #f16e00;
    border-bottom: 3px solid #f16e00;
}
