fix(Datagrid): look for id from data for initially expanded rows

[matthewgallo]

Closes #5263

The current implementation for initially expanded rows is somewhat flawed in that it only looks for the id assigned from the react-table row. This update will also check if a provided id from initialState.expandedRowIds exists within the user provided data (the original row data).

What did you change?

packages/ibm-products/src/components/Datagrid/Extensions/NestedRows/NestedRows.stories.jsx
packages/ibm-products/src/components/Datagrid/useNestedRows.js
packages/ibm-products/src/components/Datagrid/utils/makeData.js

How did you test and verify your work?

I passed an id to initialState.expandedRowIds that exists on the original row and verified the associated row is still initially expanded.
