Externalize clipboard copying to the [clippie](https://github.com/silverwind/clippie) module which I feel I can maintain outside this repo for shared benefit with my other projects. The module is feature-equivalent to the previous code and has one improvement where it sets `aria-hidden` on the fallback textarea, preventing screen readers from picking it up. Also it support `Array` of `content` as well to copy multiple items at once, in case it's ever needed.
