This LGTM, but I would like to do the update-otel separately, so all core modules point to the same commit

The go.opentelemetry.io/collector/receiver/receivertest package has been moved into a separate module on the main branch and does not have a release tag yet. Running multimod will always fail on components depending on receivertest. 🤔

Can we cover profiles in the e2e testing as well? See https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.112.0/processor/k8sattributesprocessor/e2e_test.go. Either tuning the existing tests or introducing a new one.

I have updated the e2e test. However, the telemetrygen CLI doesn't support profile signals yet. I will submit another PR to add support for profile signals to telemetrygen and then update this PR.

I have opened an issue (#36127) to track it and skip the tests with added TODOs. I would like to submit another PR to enable the profiles test and remove all TODOs from the tests once telemetrygen is ready for profiles.
