Draft Zed extension for Air

[DavisVaughan]

It seems to work but I haven't tested the download bit yet

Point Install Dev Extension at this zed/ directory and it figures out the rest
https://zed.dev/docs/extensions/developing-extensions#developing-an-extension-locally

You also need

{
  "languages": {
    "R": {
      "language_servers": ["air"]
    }
  }
}

Seeing this in the main zed logs

Looks like Zed has a very small set of capabilities right now

It probably should not set DidChangeConfigurationClientCapabilities...
