[BUG] Subtract node is only available in Maya 2024.2 and above

[chris-lesage]

🐞 Bug Report

Description

As reported in the forum, the Subtract node was only added to Maya 2024.2 and above. So any lower versions get an unknown node error when running commands that use it. http://forum.mgear-framework.com/t/mgear-5-2-1-subtract-node-issue/5152

Expected Behavior

I suggest switching to plusMinusAverage node set to minus, to get equivalent behaviour, if possible. That will work in older versions.

Actual Behavior

An unknown node error, and the code can't find the appropriate input1 and input2 attributes.

Maya Version

Maya 2023 and older. Maya 2024.1 as well.

mGear Version

mGear 5.2.1 (and possibly other versions. I don't know when Subtract was added to the code.)
