feat: ignore `gutter-output` for margin grid in `xy-cell` mixins
feat: ignore `gutter-output` for margin grid in `xy-cell` mixins

`gutter-output` cannot be set to `false` for margin grid as the gutter (margin)
is defined with the width. Gutters can only be set or reset to 0, which does
not fullful the role of `gutter-output`.

See discussion at https://github.com/zurb/foundation-sites/pull/11081

**BREAKING CHANGE**

Before:
```scss
@include xy-cell(12, $gutter-type: margin, $gutter-output: false);
@include xy-cell-static(full, $gutter-type: margin, $gutter-output: false);
```

After
```scss
@include xy-cell(12, $gutter-type: margin, $gutters: 0);
@include xy-cell-static(full, $gutter-type: margin, $gutters: 0);
```
