Need quadratic style for edge

### Describe the bug

- The official solution for more than one edges between two nodes suggested for G6 is using `quadratic` line: [https://g6.antv.vision/en/docs/manual/middle/elements/methods/multi-line](https://g6.antv.vision/en/docs/manual/middle/elements/methods/multi-line)
- However, Graphin only allows 'graphin-style': https://github.com/antvis/Graphin/blob/f578319990d545e24b340d2003522f90e3c9afdc/packages/graphin/src/Graphin.tsx#L175

- So two edges between two nodes become weird and the edges point to none of the nodes (top left on the picture):
