Adds B3 Single (`b3`) and B3 Multi (`b3multi`) as supported propagation formats in the Rust tab of the trace context propagation page. Updates the introductory paragraph and the env-var example to reflect that the Rust SDK now supports the same four propagation formats the other Datadog tracers do. Depends on the `datadog-opentelemetry` crate landing B3 support (DataDog/dd-trace-rs#253, #254, #255, #256).

What does this PR do? What is the motivation?
Adds B3 Single (
b3) and B3 Multi (b3multi) as supported propagation formats in the Rust tab oftrace_context_propagation/_index.md. The Rust SDK gains B3 support in the upcomingdatadog-opentelemetryrelease, matching the format coverage of the other Datadog tracers.Specifically:
b3,b3multi).DD_TRACE_PROPAGATION_STYLEexample to reflect the four supported formats.[3]/[4]link references inside the Rust tab so the table links resolve.Merge readiness
This depends on the B3 propagator changes landing in
DataDog/dd-trace-rsfirst:Please hold this PR until those merge and a release that includes them ships.

Additional notes
The note "
baggageis not supported in Rust" earlier in the document is unchanged and remains accurate; this PR only adds B3.
