Grouping causes rows count to increase

Describe the bug and the steps to reproduce it

1. Open https://www.mantine-react-table.com/docs/guides/aggregation-and-grouping#aggregation-grouping-example
2. See 298 as row count in table.
3. Remove grouping by state (default).
4. Footer now says there are 250 rows.

For me this is a bug, because we have 250 rows of data in table and counting grouping rows is misleading. Let's assume orders table, where you group by client and now you have more orders than really were received.

// if this is accepted as a bug I can try to send PR fixing it. I didn't look into code yet.

Do you intend to try to help solve this bug with your own PR?

Maybe, I'll investigate and start debugging

I'm not sure, but probably something like
getPrePaginationRowModel().flatRows.filter(r => !r.getIsGrouped()).length here could help.

Don't know if it's safe, will try to work with this in some spare time, but maybe this will help someone with more knowledge to push PR faster.
