v5: navbar-offcanvas color issues with navbar-dark

Created by: jakubmuda

There is a problem with colors in navbar-offcanvas. I didn't see any information about it in docs. It's a new feature so maybe I am doing something wrong so it should be mentioned in docs how to do it properly.

Just copy the navbar-offcanvas code and change color theme to dark by changing navbar-light bg-light to navbar-dark bg-dark

https://getbootstrap.com/docs/5.1/components/navbar/#offcanvas

The navbar is dark as expected with light text:

But the offcanvas is white and therefore the text is not visible.

You should also change text-reset to btn-close-white for dark navbar. In this case it should be removed, right?
