Fix conflicts for aks_preview index.json

[zhoxing-ms]

Related PR: #4778

Since the index.json PR #4753 of the previous version 0.5.65 is merged later than the PR #4759 that changed the version to 0.5.66 from setup.py, so the code in index.json from PR #4759 does not contain the contents of version 0.5.65, then the generated index.json for version 0.5.66 from this PR conflicts with the index.json for version 0.5.65
