Remove the class .nav-item from .nav-link inside the non ul or ol based navs.
This makes the consistency for .nav-item (This class will not be required on the .nav-link).
.nav-item was only required when you use .nav-fill or .nav-justified on the .nav. In other cases, it was redundant. And the purpose of .nav-item on .nav-links can be achieved via flexbox utilities as well (Mentioned in the docs also).
