v2.2.1

We're thrilled to announce the release of DGL 2.2.1. 🎉🎉🎉

Major Changes

• The supported PyTorch versions are 2.1.0/1/2, 2.2.0/1/2, 2.3.0. See install command here.
• MiniBatch in GraphBolt is refactored: seed_nodes and node_paris are replaced with unified seeds attribute through out the pipeline. Refer to the latest examples for more details. by @yxy235
• GraphBolt sampling is enabled in DistGL for node classification. See examples here.
