Update deploy_test.yml

so initially, i had to add a line for deleting some container coz i think they might have been built in some previous iteration that wasnt executed fully and couldnt be deleted. but now that the previous commit went through successfully i am assuming there are no more containers with this name..so we should be able to continue without this command
