Description

During accessibility testing, our auditor pointed out that on some pages with two or more EuiCodeBlock components, there are multiple buttons with the aria-label="Copy". This violates the WCAG 2.2 guideline on "Info and Relationships".

Let's discuss the available options for addressing this issue.

I see 2 options:

1. Update API to make possible to override aria-label attribute for Copy button
2. Using the root level aria-label attribute (already in API), do something like: Copy {rootLevelAriaLabel} code snippet
