Add XPU support for hetero examples

CHANGELOG.md

@@ -48,7 +48,7 @@ The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/).
 - Made `MessagePassing` interface thread-safe ([#9001](https://github.com/pyg-team/pytorch_geometric/pull/9001))
 - Breaking Change: Added support for `EdgeIndex` in `cugraph` GNN layers ([#8938](https://github.com/pyg-team/pytorch_geometric/pull/8937))
 - Added the `dim` arg to `torch.cross` calls ([#8918](https://github.com/pyg-team/pytorch_geometric/pull/8918))
-- Added XPU support to basic GNN examples ([#9421](https://github.com/pyg-team/pytorch_geometric/pull/9001))
