dep: update pd client for batched runtime trace regions | tidb-test=release-8.5-20260323-v8.5.5

[bb7133]

What problem does this PR solve?

Issue Number: ref #69743

Problem Summary:

tikv/pd#10988 has been merged into tikv/pd branch release-8.5-20260709-v8.5.5. TiDB branch release-8.5-20260323-v8.5.5 still depends on an older github.com/tikv/pd/client, so it does not include the batched TSO runtime trace region fix.

What changed and how does it work?

Update github.com/tikv/pd/client from v0.0.0-20260330105957-ebf9af006aac to v0.0.0-20260713030331-b294f28d9f6a, which corresponds to the merged PD release branch commit b294f28d9f6a from tikv/pd#10988.

Please run make bazel_prepare and commit the generated DEPS.bzl. Bazel still pins the old PD client, so release builds will miss this fix.

The new revision does not include ebf9af006aac, which fixed major Resource Group latency spikes. Please create a PD revision that contains both fixes.
