Update to allow for Crptography 42.0.4 or later to address many CVE

[jayreed-nava]

We have been waiting for an update to the splunk-otel package since at least November to allow for newer versions of python cryptography with fixes for many many CVE.

Can we please get an updated package with newer versions of dependencies?

Hi -- the cryptography dependency just got bumped from 42.0.2 to 42.0.4 here: #394

This change will be released after the next release of Opentelemetry Python (should be within the next week or so).
