chore: change workflow name

[rt-slalom]

secureli-437

Changes the name of the integration test workflow to smoke test.
According to the issue raised on stack overflow here, and the github documentation here, the old integration test workflow history should remain. Workflow runs must be deleted manually, and renaming the files should create a new workflow.

If the Integration Test workflow is still active after this PR is merged, it should be disabled. How to disable a workflow

Changes

• Rename .github/workflows/integration_testing.yml to .github/workflows/smoke_testing.yml
• Updated workflow name to Smoke Testing
• Updated job name and file reference to Smoke Testing in .github/workflows/publish.yml

Testing

• Not sure how to test, since this workflow will only run on main and be created when this PR is merged.
