[Debugger] Ensure all probes has a version property

[watson]

Motivation

All probes sent via Remote Config should have a root version property. For some reason, one was not present in our mocked probe configs located in tests/debugger/probes. I'm not sure why this hasn't resulted in system test errors previously since the diagnostics schema expects that a version is reported. However, without this, at least the Node.js tracer, would set version: undefined in the object before it was serialized to JSON, which would completely remove the version property from the JSON output.

Maybe they other tracers fall back to 0 if there's no version property in the probe config?

Changes

Hardcode all mocked probe configs to contain version: 0.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes (if something not related to your task is failing, you can ignore it)
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner. We're working on refining the codeowners file quickly.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed, you can merge it!
