add lowang-bh as scheduler reviewer

[lowang-bh]

hi, I have followed volcano since 2021 when I was first working on k8s cluster-schedule for ML jobs using kube-batch. I found that volcano scheduler is base on kube-batch and has continious upgrade. So I often read the PRs and volcano-scheduler source code and sometimes find some issues. I hope to become a reviewer of the volcano scheduler and better cooperate with the community.
Here is my PR about some feature enhancement and issues fix .

• fix issue #1711 about empty job queue in metrics #1722
• fix issue #2826
