Support for node 20

[ChoqueCastroLD]

When updating to node 20.4.0 I get this error no matter the otel version I try

Which compiler/version are you using?

I'm getting the same error on my system:

Using c++17 instead of c++14 seems to fix this issue:

diff --git a/binding.gyp b/binding.gyp

             "-stdlib=libc++",
             "-Wall",
             "-Werror"

But there is also a compilation warning in the latest nan: nodejs/nan#953.

So, -Werror also breaks Node.js 20 builds. But this part should not be specific to mac.

I tried running splunk-otel build in CI with those changes and it looks like linux build have some other issues as well:

Version 2.3.1 should fix the issue for Node.js 20, please reopen or let us know if it still happens.
