[TASK] Explicitly provide all fgetcsv() arguments

With [1] the 5th parameter `$escape` of `fgetcsv()` must
be provided either positional or using named arguments or a
E_DEPRECATED will be emitted since `PHP 8.4.0 RC1` [2].

This change provide now all five parameter for `fgetcsv()`
calls and thus using the positional approach to allow easier
backporting to older TYPO3 version where named arguements are
not usable.
