Example screenshots are not accurate

[asilcetin]

Example screenshots for starter templates need to be updated.

See them under: http://getbootstrap.com/docs/4.0/examples/
And inside the git repo under: docs/4.0/examples/screenshots

Nearly all navbars in the screenshots are inside containers whereas the actual templates use full-width navbars. There are also other inconsistencies such as elements, colours etc.

This is a minor issue regarding representation but still important for people who use those templates a starting point.

They will be updated in our next release thanks 👍
