Fixed PHP 8.4 deprecation (#590)

Fixed deprecation warning for str_getcsv in php 8.4, since the default
parameter will change, by providing the parameter explicitly.

Sidenote: some of the vendor packages still have the same issue with
deprecation warnings when running code maintenance tools. They should be
updated as well.

Closes #587
