Closes #5207.
Adds per-SDK enablement for OpenTelemetry request tracing to the existing "OpenTelemetry distributed tracing" section in
docs/data/overview.md, and adds theviam-sdk[tracing]install extra todocs/build-apps/setup/python.mdalongside the existing[mlmodel]extra. The server-sidetracingconfig block was already documented; this how-to addition covers the per-method child-span behavior (Go, Python, C++), the Python[tracing]extra, the C++ compile-timeVIAMCPPSDK_OPENTELEMETRY_TRACINGrequirement plus optionalTracingSpanchild spans, and using traces to pinpoint latency and failures across service boundaries. Additive only (no moves, renames, or URL changes). Sources: viamrobotics/viam-python-sdk#1223 and viamrobotics/viam-cpp-sdk#638.
