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

Browse source 
- 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.
