Reduce bootstrap-grid.css content

[julien-deramond]

Description

This PR removes some imports in bootstrap-grid.scss to lighten the content of bootstrap-grid.css which doesn't need to embed CSS vars from _root.css.

Here is the diff between dist/css/bootstrap-grid.css generated in this PR and when generated with the main branch:

Almost none of the CSS vars which were included within bootstrap-grid.css are useful for the grids so IMO can be removed from there. It means that we need to move --bs-breakpoint-* definitions in _grid.scss but I don't find it too problematic (event if they are scoped with :root).
