[golang] Activate CSS Test_Client_Stats_With_Client_Obfuscation

[ichinaski]

Motivation

APMSP-3668. dd-trace-go performs end-to-end client-side stats obfuscation negotiation (version-negotiated, no dedicated flag). Test_Client_Stats_With_Client_Obfuscation runs under the base TRACE_STATS_COMPUTATION scenario and already xpasses on the released tracer (observed on v2.9.1 in CI) while marked missing_feature.

Changes

Version-gate tests/stats/test_stats.py::Test_Client_Stats_With_Client_Obfuscation at v2.9.1 in manifests/golang.yml (was an unconditional missing_feature). The _With_Client_Obfuscation_Disabled variant stays missing_feature (APMSP-3672) — Go, like dotnet, exposes no runtime switch to disable client obfuscation, so that scenario is not applicable.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!
