Fix media-breakpoint-between (#23997)

* Fix media-breakpoint-between

When compiling .scss that uses media-breakpoint between with xs as the lower bound or xl as the upper bound, a compilation error can occur due to $min/$max being set to null, or the resulting .css can be invalid (see issue #23965).

(This is basically the same fix that was applied to media-breakpoint-only a short time ago).

* Update _breakpoints.scss

Make houndci-bot recommended changes.
