which is based on DataGrid. SimpleDataGrid is intended to give a simple
ready-to-use data grid for client side data for example.
These files will be used to define the custom design tokens per components.
They are automatically aggregated by the packages/react/cunningham.ts file,
this is why handling typescript config file was important.
