Title: Fix gutter variable

Issue #13616 was fixed by commit e06970948b963fa2fb11583533f726a3a8051967 earlier today, but I think part of the required changes accidentally got left out.

@gutter is now a parameter for the mixin, but the mixin itself still uses the old @grid-gutter-width variable.

This fixes that.
