nan tests fail on three platforms with Node.js 20.x

[Rich Trott]

https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/3297/testReport/ shows failures on win-vs2019, rhel8-s390x, and aix72-ppc64. Is someone likely to investigate these any time soon or would it be best to skip on those platforms for now? (Honest question, no judgment, just trying to figure out the best path forward.)

The rhel8-s390x and aix72-ppc64 failures are nodejs/nan#935 and almost certainly an endianness problem (no idea how easy it will be to fix).

[Alfonso Graziano]

@Trott unfortunately it is not bound to v20.x.
It also failed in this run with v18.18.

Shall we skip it for these platforms for now until a proper solution is found? (#1005)
