CI: Disable implicit bool conversion linter warning

Implicit conversion from integer to boolean and vice versa is very
common in FreeCAD due to SbBool (from coin) being defined as int. This
creates a lot of false positives that should not be addressed in code
reviews. We also use such implicit coversions in FreeCAD often in
general so that warning is usually ignored.
