cc6d6a92 - fix: pass selection mode generic to ComboBox validate type (#9795)

fix: pass selection mode generic to ComboBox validate type (#9795) ComboBoxProps was using `Validation<ComboBoxValidationValue>` without passing the `M` generic, so the validate callback's `value` field was always typed as `Key` (single mode) even with `selectionMode="multiple"`.
