Damien Picard c36c103389 I18n: Translate "Unassigned Node Tools" tool node menu 
The "Unassigned Node Tools" menu type is declared manually in a
function, and its label is not automatically translated. This commit
extracts it using `N_()`. Note that its description was already
extracted the same way.

Reported by Ye Gui in #43295.
