Deduplicate tutorials with smoke test workflows (#2315)

Summary:
`tutorials_smoke_test_on_push` was failing since `upload_artifact` has been deprecated: https://github.com/pytorch/botorch/actions/runs/8885237794

Without it, the two workflows are identical, so I deleted one and updated the other to run on both PRs & push.

Pull Request resolved: #2315

Test Plan: Successful workflow run on PR & after the PR lands
