Consider mentioning go play-space browser extension on readme

[somombo]

Hello, shameless plug here 😌.

I created the browser extension Go Ground2Space [Source-code]. The extension automatically opens the equivalent go play-space url instead of a given go-playground url.
(Note that, for now, it only supports chrome/edge but there are plans for supporting other popular browsers in future)

This extension is targeted mainly at people who are frequent or exclusive users of go play-space (instead of go-playground). It is convenient for them since, whenever they click on a random playground link somewhere (or someone shares one with them), they can rest assured that it will open up with syntax highlighting goodness!

I thought that it might be useful for such users to know that such an extension exists. Would you consider noting the existence of the extension somewhere on your repo or readme?
