Replace document.execCommand with navigator.clipboard

[mbelsky]

Issue: #10526

What I did

Replace document.execCommand with navigator.clipboard

Navigator API: clipboard support table

How to test

1. Open ?path=/story/basics-syntaxhighlighter--bordered-copy-able in examples/official-storybook
2. Click 'Copy' button
3. Check that your clipboard equals to

import { Good, Things } from 'life';

        const result = () => <Good><Things /></Good>;

        export { result as default };
      

(clipboard output is not formatted on next branch too. I think it better to fix in another pr)

Use @storybook/client-logger instead?
