Label/LabelGroup - update how editable labels are conveyed to assistive tech

[thatblindgeye]

Is this a new component or an extension of an existing one?
Label

Describe the feature
Currently editable labels in both Label and Label Group examples use aria-label to notify users that the Label is editable. This overrides the Label content, which can cause confusion/disparity since a "remove" button will reference the Label content (not the aria-label).

A quick solution would be to update examples so that the aria-label is concatenated from something along the lines of "Editable label: ${labelContent}

Are there visuals for this feature? If applicable, please include examples for each state and for varying widths
