Update PROMETHEUS query rules

在 https://jihulab.com/jihulab/jh-infra/gitlab-cn-ops/-/merge_requests/43 中，更新了gitaly节点的relabel规则：

saas-staging-gitaly-1              # type=gitaly,gitaly-type=gitaly-cluster
saas-gitaly-3                      # type=gitaly,gitaly-type=gitaly-cluster
saas-gitaly-shards-ssd-1           # type=gitaly,gitaly-type=gitaly-shards-ssd
saas-staging-gitaly-shards-ssd-2   # type=gitaly,gitaly-type=gitaly-shards-ssd
saas-gitaly-shards-hdd-1           # type=gitaly,gitaly-type=gitaly-shards-hdd
saas-staging-gitaly-shards-hdd-2   # type=gitaly,gitaly-type=gitaly-shards-hdd
saas-gitaly-shards-zfs-1           # type=gitaly,gitaly-type=gitaly-shards-zfs
saas-staging-gitaly-shards-zfs-2   # type=gitaly,gitaly-type=gitaly-shards-zfs

查询规则也需要相应修改。
