[Python][Bug]Update the dotpromptz package publishing flow

[MengqinShen]

Current workflow "publish_python_package.yml" handles both publishing handlebarrz and dotpromptz . as handlebarrz is already handled by "publish_rust_package.yml", we need to modify "publish_python_package.yml" accordingly

1. rename workflow name and file name to be clear indicting its functionality
2. delete handlebarrz publishing flow
3. update dotpromptz workflow
4. add smoke test to handlebarrz as dependency is checked before publishing dotpromptz
