Trigger the Sort Merge Join benchmark using the GitHub action

Would be great to have an opportunity to trigger SMJ benches separately during CI/CD

The action has tpch hard coded here: https://github.com/apache/arrow-datafusion/blob/b54adb36b855f198b5098fdb3e4cdf1934818efd/.github/workflows/pr_benchmarks.yml#L41-L51

We could probably add SMJ (or maybe add another command like /benchmark smj 🤔

The CICD benchmark has been removed.(#11165)
I think we should close the issue.
