build: Fix opentelemetry-cpp build failure on Noble

The version of the opentelemetry-cpp we currently use has a missing
include in the Jaeger exporter.

Newer versions remove the Jaeger exporter entirely.

While upgrading sometime would be good, it doesn't have to happen
right now.

Thus do I hereby update the opentelemetry-cpp submodule.
