Persist grouped row expand or collapse state

The Syncfusion Blazor DataGrid offers the ability to persist the expand or collapse state of grouped rows across various data operations such as paging, sorting, filtering, and editing. By default, these operations reset the grouped rows to their initial collapsed or expanded state. To retain the current state of grouped rows and ensure a consistent user experience, set the GridGroupSettings.PersistGroupState property to true. This also applies when using external grouping methods like ExpandAllGroupAsync and CollapseAllGroupAsync.
