Expert requires `--stdio` flag

[doorgan]

Hi! Thanks for this extension!

I'm not a zed user myself, but we had reports of zed users not being able to use Expert in the latest nightly builds. A few days ago we started requiring the --stdio flag to run expert(or --port <port> for tcp mode), otherwise it defaults to show a help message.

My understanding is that this can be configured by users with something like this:

"lsp": {
  "expert": {
    "binary": {
      "arguments": ["--stdio"]
    }
  }
}

But this should be the default behavior. I'm not familiar with zed's extension ecosystem or rust, but I can take a stab at fixing this later.
Thanks!
