[BUG] GroupBy schema shapes are incorrect when using `list` agg on list column

Describe the bug
The shapes recorded by the GroupBy operator are incorrect when running the list aggregation on a column that already contains list values.
Steps/Code to reproduce bug
Details here: #1760 (comment)
Expected behavior
The shape should be adjusted to add the additional dimension that's created by this aggregation.
Additional context
This bug was introduced by #1760, but should be very low impact until we start using shape information directly (instead of relying on it indirectly through is_list and is_ragged.)
