Describe the bug

parentId and getParentRow returns undefined for leafRows that are grouped by a given column

Your minimal, reproducible example

https://codesandbox.io/s/row-grouping-forked-pg5nco

Steps to reproduce

1. Go to https://codesandbox.io/s/row-grouping-forked-pg5nco
2. Expand/Collapse the "single" status
3. Notice the parentId is undefined and the getParentRow in the console is undefined too

Expected behavior

I expected the parentId to reference the "virtual" aggregatedGroupedRow tanstack table creates internally.

How often does this bug happen?

Every time

Additional context

I think because tanstack table is creating a "virtual/fake" row for the grouping, that row id should be assigned to its subRows so we don't lose its parenting references
