[Service Bus] Prepare azure-servicebus 8.0.0 for release

[Eldert Grootenboer (EldertGrootenboer)]

Problem

The five Azure Service Bus client libraries are still configured for
prerelease versions, and their release notes are split across preview
CHANGELOG entries.

Fix

Set each library to its stable GA version and consolidate the complete preview
line under a dated October 6, 2026 release entry.

Changes

• sdk/servicebus/azure-servicebus/CHANGELOG.md
• sdk/servicebus/azure-servicebus/azure/servicebus/_version.py

[Pilot] PR Pipeline Failure Analysis

What failed

The python - storage check failed on Azure Pipelines build
6846697,
with the Build_Linux job reported as CANCELLED (a downstream/related job in the same build was
cancelled after the failure). The automated CLI analysis (azsdk ci analyze) was run against this
PR, but it returned no pipeline log data (azure_pipeline_analyses was empty) and no failed test
records (pipeline-test-results.txt was empty). This Azure DevOps pipeline is internal to the
azure-sdk organization, and this workflow does not have the user's Azure DevOps identity, so it
cannot pull the build logs or test artifacts needed to determine the root cause.

Recommended next steps

• The workflow does not have the user's Azure DevOps identity and cannot access this internal
  pipeline's logs or test results. Analyze it locally by running the following command while
  authenticated to Azure DevOps (e.g. via az login):

azsdk ci analyze https://github.com/Azure/azure-sdk-for-python/pull/49050 --output json

• Alternatively, open the build directly to inspect logs:
  https://dev.azure.com/azure-sdk/590cfd2a-581c-4dcb-a12e-6568ce786175/_build/results?buildId=6846697
