Update dedupe workflow to have correct name (#5327)

* Refactor issue dedupe workflows to call reusable workflow

Replace inline workflow logic in all three issue dedup files with thin
callers to opensearch-project/opensearch-build/.github/workflows/issue-dedupe.yml@main.
This centralizes the dedupe logic (detect, auto-close, remove-label) into
a single reusable workflow, reducing per-repo maintenance burden.

* Temporarily point dedupe workflows to personal fork for testing

Point reusable workflow references to qianheng-aws/opensearch-build
branch add-issue-dedupe-workflow until the upstream PR is merged.

- Three caller workflows now delegate to opensearch-build reusable workflows
- Remove .claude/commands/dedupe.md (prompt now lives in opensearch-build)
- Remove scripts/comment-on-duplicates.sh (logic inlined in reusable workflow)

- Point to opensearch-project/opensearch-build@main
