Without this change we're missing the BaggageTextMapPropagator for
OTel. This means that we're not propagating remote-fields
(only baggage via the 'baggage' field).
With this change we're adding the missing propagator as
THE LAST entry in the composite TextMapPropagator. It has to be
last cause with the latest Snapshots of Micrometer Tracing it
will append the remote field baggage to existing baggage in the
context extracted via the W3CBaggagePropagator.
