[testbed] disable setting grpc log

[codeboten]

This is causing a race condition with the InProcessCollector.

This change includes:

• set the flag to disable setting the grpc logger from the InProcessCollector
• make update-otel
• update calls to featuregate as a result of open-telemetry/opentelemetry-collector@addf0ef
• update tests as a result of open-telemetry/opentelemetry-collector@5658f35

Fixes #9557

@codeboten please run make update-otel

This error is caused by a change in CopyTo where we don't copy empty array, we live it nil in that case.

@codeboten @bogdandrutu do you think we can update the test to change original slices to nil? Otherwise I can also update the CopyTo to make exact copy of slices

[codeboten]

@dmitryax I updated the test
