Fix GitHub Primer tooltips link (#479)

blur() results in a loss/reset of keyboard focus, meaning keyboard users usually get thrown right back to the start of the page. Instead, this moves focus back to the trigger (which had the focus when the trigger was activated).
As with the proposed fix in https://github.com/zenorocha/clipboard.js/pull/418 this obviously results in the focus styles (like the default outline, unless suppressed) being applied to the trigger (see the related PR for rationale and future fix using `:focus-ring`)

+Each application has different design needs, that's why clipboard.js does not include any CSS or built-in tooltip solution.

+The tooltips you see on the [demo site](https://clipboardjs.com/) were built using [GitHub's Primer](https://github.com/primer/primer-css/tree/master/modules/primer-tooltips). You may want to check that out if you're looking for a similar look and feel.
