Thumbnails with CrealityPrint ot showing

[RealMunichMan]

Is your feature request related to a problem? Please describe

When I create gcode-files with CP 5.1 and upload them to the k1max-printer (default Creality Webinterface) Fluidd doesn't show the thumbnails.
Even when uploading the files to Fluidd the thumbnails are not shown. Manipulating metadata.py helps for the manual uploaded files, but is identified as a manipulation by the update-manager.

You have to add one line "'Creality': r"generated by Creality_Print\s(.*)\son", in file /usr/data/moonraker/moonraker/moonraker/components/file_manager/metadata.py to class PrusaSlicer(BaseSlicer):

Is there a solution for the thumbnails in both upload-scenarios?

Describe the solution you'd like

Adding the line "'Creality': r"generated by Creality_Print\s(.*)\son" to the BaseSlicer-class
