1. Negative datum values are not valid for the constraint with index - no string in Crowdin

This is all being generated in SketchObjectPyImp.cpp, and there are a ton of untranslated user-facing strings in there. I've started a forums discussion about this file: https://forum.freecad.org/viewtopic.php?t=77673

Thank you for your inquisitiveness and not belittling the subject.

I think I have come with a solution for the dynamically generated strings:

I need to beautify the code, but I should be able to PR it for the weekend.

Any number of parameters:

       else if (err == -2) {
            PyError_SetEnhancedString(
                QT_TRANSLATE_NOOP("Notifications",
                                  "Datum {} for the constraint with index {}  is invalid"),
                (const char*)Quantity.getUserString().toUtf8(),
                Index);
        }
        else if (err == -4) {
            PyError_SetEnhancedString(
                QT_TRANSLATE_NOOP(
                    "Notifications",
                    "Negative datum values are not valid for the constraint with index {}"),
                Index);
        }

Parameters can be strings and then, they will be translated too (if marked for translation).

I uses the format style placeholders.
