Add Mermaid copy button, avoid unnecessary tooltip hide (#22225)

- Add Copy button to mermaid diagrams which copies their source. - Set tippy to not hide on click and avoid tooltip re-creation for temporary tooltips. This avoids hide and show when copying repo url. Popovers still hide the tooltip as usual. <img width="815" alt="Screenshot 2022-12-23 at 14 02 32" src="https://user-images.githubusercontent.com/115237/209341696-98e30953-f246-46d9-9157-2ececfd791c9.png"> Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: KN4CK3R <admin@oldschoolhack.me>
