🐞 Incorrect focus ring shape for buttons.

### Description

Focus ring shape for buttons are incorrect.

For AppKit controls, focus rings for buttons with images automatically get their shape according to the image content, or it could be arbitrarily drawn by implementing `NSCell.drawFocusRingMask(withFrame:in:)`.

For SwiftUI, current I have no idea how to implement such behavior. `View.contentShape(_:eoFill:)` may help, but unless we have a efficient way to convert SF Symbols to `CGPath`s. The [only article I could find](https://maheepk.net/posts/converting-sf-symbols-to-shapes/) utilizes `Vision.framework` to do this, which is too heavy I believe.

### To Reproduce

1. Enable keyboard navigation on system settings.

2. Open CodeEdit and see the focus ring shape.

### Expected Behavior

Focus rings should be the same shape as the button image.
