Changed otlphttp to otlp_http in otel-config.yaml due to deprecation of the old name

[gfoidl]

Cf. open-telemetry/opentelemetry-collector#14397 and it's documented in the README.md of the HTTP exporter.

Note: with the old name it still works, but some warnings get logged.

Thanks for the PR.

Do you have an example of where these are logged? I wonder if it's something we could detect in CI in the future to avoid this sort of thing (i.e. break CI when something changes).

Runnint with ENABLE_LOGS_OTELCOL=true the logs showed

So the warn could be grepped quite easily.
Unfortunately I'm not familiar with the CI here, so I would be happy if this could be addressed by someone else (I know your comment was not an intention that I should do it anyway).
