Update git submodules

* Update releases from branch 'master'
  to b6318616052ba83de896d441396fc7c717b72411
  - Merge "[tool] Do not add reviewer to patch for unmaintained"
  - [tool] Do not add reviewer to patch for unmaintained

    Unmainained branches are not maintained by project teams, thus,
    they don't need PTL or release liaison approval. So let's not
    spam them.

    These patches are usually the patches where we move an unmaintained
    branch to End of Life. As we don't release anything out of a branch
    in unmaintained state.
