tour: replace 'argument lists' with 'parameters list' to be accurate

Just for the sake of accuracy and slightly better reading comprehension for those who implicitly differentiate between arguments and parameters, a minor wording change could be great. By reading comprehension I mean it will be a slightly less overhead for the group of people who know that this difference technically exists. These people will inherently as the first thought think about the function call and the type declaration in the argument list (as mentioned in the tour), which never happens. They will then visualise function definition, this breaks the flow when we are learning something. I personally experienced this and although I am aware that its such a minor thing but still I feel it can be marked as something like a 'Quality of Life' issue.
