Adjust the default values for ironing_inset so that the slice result remains the same

The slicer has been adjusted to give this setting a more logical function: It should be an inset of the outer edge of ironing as it appears in layer view where the lines are made thinner according to their flow.
As a result all of the slices with ironing have changed. This adjusts the setting value so that the actual slice output will not change, just the appearance of the setting.

Contributes to issue CURA-7318.
