Tyler HelmuthandGitHub 37d10c83ea [exporter/logging] Remove logging exporter (#11037)
#### Description

It is September, which means we get to remove this deprecated component.

- The helm chart was updated to exclude the logging exporter already:
https://github.com/open-telemetry/opentelemetry-helm-charts/blob/main/charts/opentelemetry-collector/UPGRADING.md#0840-to-0850.
- The Operator references have been updated:
https://github.com/open-telemetry/opentelemetry-operator/pull/3259.
- Opentelemetry.io site final references to update:
https://github.com/open-telemetry/opentelemetry.io/pull/5143
