[PWGCF] Super minor fix to comment

Cleans up a spurious `*/` in a comment line (should be harmless!). 

For now, this is the easiest way to fix a problem in the automatically generated Data Model page in our analysis documentation [1]. A better fix is to adjust the set of python scripts that parse the code: this will be pursued in continuation, but the first priority is to have some version of the auto-generated doc page for the tutorial.
