fix(dashboards): Fix trigger for single value global filter selector (#104107)

For non multi select filters, we don't externally manage staged filter
values (which we do for multi selects via `HybridFilter`). So instead of
passing in staged values into the trigger for single select filters, we
should pass in the actual active filter values parsed from the global
filter value.
