Replace clipboard.js with async clipboard api (#15899)

Use async clipboard api [1] over this dependency, saving around 10kB
bundle size before minify while delivering the same functionality.

The issue comment button works but does not have a popup indication. We
could add some toast-style notifications in the future to fix that but I
think it's out of scope of this PR.
