docs: fix terminology - 'argument' to 'parameter' in tutorial

Fixes #8375

The tutorial incorrectly used 'argument' when referring to the function

- Parameter is the variable in the function declaration
- Argument is the actual value passed when calling the function

This change improves accuracy and helps learners understand the
distinction between these two important programming concepts.
