ci: Failing node-14.x and node-15.x

[amdoku]

The inspect-scenario test is failing if the member hashmap is inspected with v8 inspect <address>.
This is due to the removal of symbol class_JSArrayBufferView__buffer__Object

This was done in https://chromium-review.googlesource.com/c/v8/v8/+/1278014 and nodejs/node-v8#84 - was this deliberate as JSArrayBufferView has been deprecated?

Testing with Node14.3.0:
