The headerRenderer is ignored when using GridSortColumn

[johannest]

Description of the bug

The headerRenderer seems to work only for standard GridColumn, but is ignored when using GridSortColumn

Minimal reproducible example

<Grid items={people}>
              <GridColumn path="id" headerRenderer={() => {
                  return <div>TestHeader1</div>
              }}
              />
              <GridSortColumn path="name"
                              headerRenderer={() => {
                                  return <div>TestHeader2</div>
                              }}
              />
          </Grid>

Expected behavior

The headerRenderer would work also for GridSortColumn.

Actual behavior

The column name is got from the path instead of headerRenderer:

Thanks for the issue. The current behavior is by design - see the comment in the code about using default header renderer.
