azure_devops: pin add_comment to documented api-version 7.0-preview.3

Microsoft's Add Comments docs only publish 7.0-preview.3 (the 7.2 view falls back to the 7.0 page). Get Comments stays on the documented 7.2-preview.4. Matches what's strictly in the Azure DevOps REST API reference rather than relying on undocumented version behavior.
