Why does adding a comma fix my configuration validation error?

Trailing commas are required for string_list parameters in https://github.com/E3SM-Project/zppy/blob/main/zppy/templates/default.ini. Since you can specify multiple year sets with years, that is a string_list parameter. Something like the www or partition parameters only accept one string, so no trailing comma is required. This will hopefully be addressed in #281.

Update: As reported in #319, the validator no longer warns of a trailing comma. With #338, zppy will properly interpret years even if the user misses the trailing comma.
