This looks great! I'm not sure why but for me it's announcing 'Copied' twice:

for me inside storybook it does not repeat the text in the voiceover dialog, it just reads it twice

but this seems to be only in storybook, I can't reproduce it when viewing the component outside of storybook or even in the storybook canvas on a new tab

Fix looks great! Confirmed on MacOS voiceover util, getting 1 "Copied!" when the button is clicked. No longer seeing the issue where CodeSnippet is announced as an editable text field as well so this should take care of #2523
