fix(node-core): Shut down OTel TraceProvider when calling Sentry.close()

[Lms24]

This PR ensures we shut down the SDKs internal OTel TraceProvider (if internal OTel SDK is intialized), when calling Sentry.close() (or rather NodeClient::close). Also added a couple of tests for client report and log flusher intervals.

Thanks for improving this! Wondering if we should backport this to v9 as well 🤔.

We could but I don't think the user impact is that large.
