Subject: [PATCH] Avoid "KeyError: material_name" crash in Fedora

    Traceback (most recent call last):
      File "/usr/lib/python3.11/site-packages/UM/Qt/ListModel.py", line 54, in data
        return self._items[index.row()][self._role_names[role].decode("utf-8")]
               ~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    KeyError: 'material_name'

Downstream report: https://bugzilla.redhat.com/show_bug.cgi?id=2252195
Community: https://community.ultimaker.com/topic/44538-cura-53-crashs-at-startup/

For reasons unknown, this crash does not happen with the AppImage.

Nevertheless, in 2baada8a70b15dd87948a25855e17d15b0ece58c
material_name was added as a role, not material_label.
Reaming the field in the sentinel extruder makes the crash go away.
