Getting settings based on initial_extruder_nr in machine start gcode outputs wrong format

[ansonl]

Cura Version

5.6

Operating System

Windows 10

Printer

Ultimaker 2+ DXU / Any printer

Reproduction steps

1. Have machine start gcode that accesses an extruder specific setting based on initial_extruder_nr.

M104 T{initial_extruder_nr} S{material_print_temperature_layer_0, initial_extruder_nr}

2. Slice and view the gcode

Mentioned and related to
#17894
#17890

Actual results

The gcode is evaluated as:

M104 T0 S(200, 0)

which is not valid format. The output of {material_print_temperature_layer_0, initial_extruder_nr} should return the material_print_temperature_layer_0 for initial_extruder_nr extruder and not in parantheses.

Expected results

Previously in Cura 5.4 the gcode is correctly evaluated as:

M104 T0 S200
