ATR-27293: Quick fix for misconfigured pixel info dumper

The changes in !57863 (merged) mean that PixelPrepDataToxAOD will print hundreds of warnings per event as it tries to dump information that we don't need for the studies in ATR-27293. This MR sets WriteNNinformation=False, which should also reduce the size of our outputs a bit.

Marking as urgent bugfix since it's blocking our production. I'm also tagging @sargyrop, the b-tagging group's SI cluster data ninja, and @srettie, who might have ideas for a longer term fix.
