Documentation about checking sc verification status is completely missing

[RaresGeo]

Issue

There is no documentation on how to use the websocket for checking sc verification status in the documentation, nor even any mention of it

In Issues and PRs I have seen mention of a websocket, I have also seen it directly in use in a Blockscout fork, but the documentation provides no information on how to use it.

What I need it for

I just need a way to check the verification status of a smart contract
