Describe the problem

REPL is an awesome tool to help people learn Svelte. A good example for that is StackOverflow where I add a REPL to almost all my svelte related answers/questions. The problem is that there is no 'common' way to share the REPL link other than the link itself so you will see in many answers stuff like:

Have a look at the REPL
Here is an example: https://svelte.dev/repl/hello-world?version=3.42.2
...

It is therefore more or less difficult to find the final example quickly in the text where other platforms such as codesandbox provides a button that is markdown/html that you can easily copy/paste like:

[![Edit cranky-boyd-3qqnq](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/cranky-boyd-3qqnq?fontsize=14&hidenavigation=1&theme=dark)

Describe the proposed solution

Would be nice in the REPL's AppControls to add a share button that will open a panel that proposes you to copy the REPL link or the markdown/html button code like:

TODOS:

• create button svg
• host static svg on the svelte site
• add control button to open panel that includes:
  • a button to copy the URL
  • 2 textareas that contains the html/markdown of the button and a preview of it

This isn't a lot of work and I would be glad to help the svelte ecosystem that I enjoy so much. I can take care of this one if everyone agree 😄
