Support for errors.haskell.org?

**Describe the solution you'd like**

I'm not sure if it's out of scope, but would it be a good idea to have this extension support errors.haskell.org?

I could ctrl-click on an error code and it would show me a little window to explain what the error means, and allow me to go further and open it in a new tab or browser window if I wanted.

**Describe alternatives you've considered**

It could be a different repo if it's completely out of scope. I've not made these plugins before.
