🐛[BUG] Can not custom tooltip names in DualAxes chart

[gicungdc123]

🐛 bug 描述 [详细地描述 bug，让大家都能理解]

Unable to customize tooltip names in DualAxes chart component from ant-design-charts. Both array and function approaches in the tooltip configuration are not working as expected. While the value and color properties work correctly, the custom name property is not being applied to the tooltip display.

📷 复现步骤 [清晰描述复现步骤，让别人也能看到问题]

1. Create a DualAxes chart with two line series
2. Try to customize tooltip names using either:
   • Function approach: tooltip: () => ({name: "test", value: 123})
   • Array approach: tooltip: [{name: 'aaaa', color: "red"}]
3. Render the chart
4. Hover over data points

🏞 期望结果 [描述你原本期望看到的结果]

• When hovering over the first line series, tooltip should show "test" as the name
• When hovering over the second line series, tooltip should show "aaaa" as the name
