Retract googlecloud exporter releases that don't have logging (open-telemetry#28884)

**Description:**

Logging was broken after
open-telemetry#25900
(released in v0.84.0). It is fixed by
open-telemetry/opentelemetry-collector#8792,
which will be released in v0.89.0. This will help with any distributions
that include the googlecloud exporter components.
