[HGrid] Hierarchical Grid Advanced Filtering sample column types

Blazor Hierarchical Grid Advanced Filtering Example column types are not configured correctly:

<!-- .... -->
<IgbColumn
  Field="Debut"
  Header="Debut"
  DataType="GridColumnDataType.Number"
></IgbColumn>
<IgbColumn
  Field="GrammyNominations"
  Header="Grammy Nominations"
  DataType="GridColumnDataType.String"
></IgbColumn>
<IgbColumn
  Field="GrammyAwards"
  Header="Grammy Awards"
  DataType="GridColumnDataType.String"
></IgbColumn>
<!-- .... -->

That makes the display odd on the Debut which is clearly an year and forces string filters on the numeric Grammy columns:

The artist names are fairly unique and only the 2 other Grammy columns are allowed for filtering, leaving very little meaningful filters to apply in the sample, beyond Nominations = 2 which works as string as well at least.

Fix the column types and/or re-evaluate the data source used for the sample if it doesn't offer enough to showcase the filtering functionality.

PS: Same seems to be true for WC and React, might be a Xplat sample

Also noticed the Angular sample does have the child schema configured and allow for much more complicated queries and start with one as well: https://www.infragistics.com/products/ignite-ui-angular/angular/components/hierarchicalgrid/advanced-filtering
Would be nice if this can be equalized.
