[parametric] Update parametric tests for b3 trace context propagation headers

[zacharycmontoya]

Description

Updates the test skip annotations for Ruby and C++ b3 trace context propagation header tests, including unskipping tests for Ruby on new tracer versions.

Motivation

Keeps the parametric test skip reasons up-to-date so we have a better understanding of why they are currently being skipped.

Reviewer checklist

• Check what scenarios are modified. If needed, add the relevant label (run-parametric-scenario, run-profiling-scenario...). If this PR modifies any system-tests internal, then add the run-all-scenarios label (more info).
• CI is green
  • If not, failing jobs are not related to this change (and you are 100% sure about this statement)
• if any of build-some-image label is present
  1. is the image labl have been updated ?
  2. just before merging, locally build and push the image to hub.docker.com
