Update playground URL as content is changed

[nguerrera]

Somehow https://sharplab.io manages to update the URL in my browser as I type and so I don't need to "save" to share a C# repro, I can just copy the URL instinctively and it works. I often forget to save when using our playground and I think it's because I got used to this sharplab behavior in a previous life. Can we match this feature?
