### Bug report

The Grid columns do not expose the ClientTemplateHandler() method. It is available in Telerik UI for ASP.NET Core since version 2023.1.314.

### Reproduction of the problem

columns.Bound(p => p.IsAlwaysIncluded).ClientTemplateHandler("myColTemplate");

<script>
function myColTemplate(data) {
  return `<div>${data.IsAlwaysIncluded}</div>`
}
</script>

The ClientTemplateHandler() method must be exposed for the Grid columns.

### Environment

Telerik UI for ASP.NET MVC version: 2023.1.425
* **Browser: [all]
