[ANN] Websocket - High level API for Server and Client with documentation

@avik
Could you help with deprecating the old package please.
I am looking at this post , but am a bit confused.

Setting the upper bound: I assume this is in Project.toml [compat] - could you give an example of the value

just send a PR to metadata to add the upper bound to all released versions of the package.

Any idea how to do that?

Or is there a formal way to do the whole deprecation procedure?
