feat: adds disableGroupBy to fields admin props (#14017)

### What?

Adds a new `disableGroupBy` admin config property for fields to control
their visibility in the list view GroupBy dropdown.

### Why

Previously, the GroupByBuilder was incorrectly using `disableListFilter`
to determine which fields to show in the group-by dropdown.

### How

- Added new `disableGroupBy` property to the field admin config types.
- Updated `GroupByBuilder` to filter fields based on `disableGroupBy`
instead of `disableListFilter`
