[CURA-12119] Fix Cura 5.8 Material Export

[Frederic98]

Description

CURA-12119
Upon exporting a .xml.fdm_material profile, Cura writes a 0/0.0 or 1/1.0 as yes or no. The UltiMaker printers then can't import these profiles, as it expects a float in those fields. This PR solves this by explicitly checking if the value is a boolean before converting it to yes/no.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?
