Update 'fdmprinter.def.json'

[GregValiant]

This will be a draft. The changes to the tooltips should be OK, but the others I'm not 100% sure on.

Alter two settings:
'material_initial_print_temperature' and 'material_final_print_temperature'
Change the tooltips to better describe the settings (the current wording is not clear), and change the "enabled" logic to include " and machine_extruder_count > 1". (That will need to be checked but it doesn't appear that the settings are used for single extruder prints.)
Tooltip changes will of course require translation changes.
Changed the "type" from float to int as most machines aren't really set up for 1/100 of a degree.
Changed the minimum_value from "-273.15" to "0" because it was just silly.
Changed the maximum_value
Changed the default value from 200 to material_print_temperature

This fixes... OR This improves... -->

This is in response to a couple of bug reports including #20168 and #19190 and maybe #14019

Tooltip change and number of extruders check is good. The setting is for multi-extruder printers mainly for when a switch happens.

I would not change the other settings as there could be side effects.
So I've heard so many stories about people printing all kinds of stuff on FDM printers, ranging from metal to chocolate to ceramics to ice-cream [Why are you against ice-cream printers :)] So while the range for average user might not be useful, it allows for creativity and experimentation. Same with the float vs int.
That's just my personal 2 cents about this.

Hah! Gotcha.
Even ice dream won't print at absolute zero.

I reverted everything except for the tooltips and the "enabled" logic.

Around -190 is the sweet spot xD with liquid nitrogen but I think the original implementation was like: "If you wanna do something wrong, do it right" and went for the easy sure way. (these are just speculations, any similarities between this and any character, real or fictional is completely accidental).

Way off topic, I bought a "Chocolate" extruder system. It worked OK except that the build plate needed that liquid nitrogen system. Everything just turned onto a blob of chocolate. Mind you, I'm not saying I didn't eat the scrap, but the prints didn't turn out at all. The entire gizmo has been sitting on a shelf for 2 years.

I was going to add a "cold air duct" to the layer cooling fan. Probably draw the air across a bucket of ice before blowing it on the print. I gave up when I tried to design the duct as it would constantly be moving with the X axis and moving up in the Z.

The rest of the chocolate was good though.
