chore: revert telemetry stabilization

Partially revert Python PR #788 as a release contingency.

This reverts commit 8bb88f5 for the
telemetry-exporter package and RELEASING.md only. Files under
packages/aws-durable-execution-sdk-python are intentionally left unchanged
so the core plugin interface is unaffected.

Exporter publishing configuration remains unchanged.
