Add copy button to markdown code blocks (#17638)
* Add copy button to markdown code blocks
Done mostly in JS because I think it's better not to try getting buttons
past the markup sanitizer.
* add svg module tests
* fix sanitizer regexp
* remove outdated comment
* vertically center button in issue comments as well
* add comment to css
* fix undefined on view file line copy
* combine animation less files
* Update modules/markup/markdown/markdown.go

* remove unused var
* remove unused localization
* minor css tweaks to the button
