Subject: [PATCH] Align the deploy script for smartswitch dark mode (#20415)

* Align the deploy script with community for smartswitch dark mode

* fix issue deploy_mg issue

We don't need to handle the parameters for the Ansible playbook individually; they can be passed to Ansible as a whole using $@.
