This PR fixes #32658 (closed) by setting the bs-gutter-x variable when the make-container() mixin is called. This is similar to what's done in make-row().
I noticed this when placing a navbar inside a column. The gutters are overridden by the row class, which doubles the container's class. Redefining the gutter-x variable in make-container() seemed like the simplest solution.
