+Charts: improve pie semi circle chart composition


Removing the label and note props is a breaking API change. Please mark this as a breaking change in the changelog (e.g., Significance: major and/or Type: breaking-change) and include a brief migration note showing how to render labels via children (Group/Text or PieSemiCircleChart.SVG).

Suggested change

Significance: minor

Type: changed

Charts: improve pie semi circle chart composition

Significance: major

Type: breaking-change

Charts: improve pie semi circle chart composition

Breaking change: The `label` and `note` props have been removed from PieSemiCircleChart. To render labels, use children components such as `<Group><Text /></Group>` or render SVG elements directly via `PieSemiCircleChart.SVG`.

Migration note:

Before:

<PieSemiCircleChart label="My Label" note="Some note" ... />

After:

<PieSemiCircleChart ...>

<Group>

<Text>My Label</Text>

<Text>Some note</Text>

</Group>

</PieSemiCircleChart>

// Or use PieSemiCircleChart.SVG for custom SVG rendering.

I don't think the semi-circle chart label and note props are currently being used by any consumers, so I don't think it needs to be a significant/major change in the changelog. I'm open to having my mind changed on this, but at this time I don't think this feedback is necessary.

This PR did not change code coverage!

That could be good or bad, depending on the situation. Everything covered before, and still is? Great! Nothing was covered before? Not so great. 🤷

I've spent a while reviewing these changes, and confirmed they would be breaking for woo analytics. I don't think at this time the small benefits are worth pushing forward with this PR and I think that it would be better as a part of a larger tidy up / refactor later. So closing this up in the meantime.
