[ci] Unfork runtime_commit_artifacts

[poteto]

Stack from ghstack (oldest at bottom):

• -> [ci] Unfork runtime_commit_artifacts #30477
• [ci] Add commit steps to new runtime_commit_artifacts_v2 #30476

Promotes v2 to the primary workflow file so that we don't double write
to the protected branches.

Note: this may break DiffTrain temporarily, I will fix forward if so
