What is the current behavior (link to any open issues here)?

OTel collector 0.125.0 fails to run with our current transform processor configuration for postgres logs.

What is the new behavior (if this is a feature change)?

• Breaking change (fix or feature that would cause existing functionality to change)

OTel collector 0.125.0 will now run; however, these changes are not backwards compatible with collector 0.119.0.

Other Information:

The otel-logging-and-metrics kuttl test will fail here as this change to the operator is not compatible with the 0.119.0 collector. Once the 0.125.0 collector image is released, the kuttl test will start passing again.
