[data grid] Row grouping negative filtering does not work

[GabrielVooDB]

Steps to reproduce

Steps:

1. Open the Row grouping documentation: https://mui.com/x/react-data-grid/row-grouping/
2. Add the following filter filter on the Company column: does not contain Disney
3. Note that unlike the positive filter, Disney still appear in the list

Current behavior

Only the positive filter seem to work, so putting contain Disney as a filter does show only the Disney row, but changing it to does not contain still shows that rows.

Expected behavior

When using the does not contain filter on a row grouping with the Disney value, I expect the Disney row to be excluded.
