attrs for line arrows are taken from the parent line instead of the arrow object

I tried using the form at https://antv-issue-helper.surge.sh but it was not working.

This issue is in @antv/g-svg 0.5.6. I know this is an old version, but I would like to open a PR to fix it. If I do so, would it be possible to release a version 0.5.7? This bug is affecting `@antv/g6`, which currently depends on `"@antv/g-svg": "^0.5.1",` (in the `@antv/g6-pc` package.) If we can release a 0.5.7 to fix this, I would then open a PR to upgrade `@antv/g6` to use 0.5.7.

Here is an example of the issue:
https://codesandbox.io/s/wild-rain-mhgy08?file=/src/index.js:0-431

The arrow should have a blue fill and green stroke, but instead it uses the stroke and fill from the parent line shape.

Result when using `@antv/g-svg`:


Expected result (this is using `@antv/g-canvas`, although I had to edit the `path` of the arrow slightly to get the same shape):


Would you accept a PR from me to fix this?

Start by reproducing the issue in the linked CodeSandbox with @antv/g-svg 0.5.6, then trace the arrow rendering behavior in the G repository. Done means line arrows use their own blue fill and green stroke rather than inheriting the parent line's attributes, while preserving the reported shape.
