doc: document ES2022's Error "cause" property

Rodrigo Muino Tomonari requested to merge github/fork/ide/@ide/error-cause-docs into main

ES2022 adds an options parameter to the Error constructor. If the options argument contains a property named cause, the property's value is assigned to a non-enumerable property named cause on the newly created error. The cause property is not referenced anywhere else in the ES2022/2023 specifications. It is for error-formatting software like util.inspect() to consume.

The cause property was added in V8 9.3, which was added to Node 16.9.0.
