Describe the feature

When the editor (client in this case) does not handle a telemetry event, the Zed app log may become flooded with messages like the following:

2024-08-15T14:17:20.621663Z [INFO] Language server with id <NN> sent unhandled notification telemetry/event:

{
  "measurements": {
    "elixir_ls.lsp_request_time": 0
  },
  "name": "lsp_request",
  "properties": {
    "elixir_ls.elixir_release": "1.14",
    "elixir_ls.elixir_version": "1.14.5",
    "elixir_ls.erts_version": "13.2.2.3",
    "elixir_ls.lsp_command": "textDocument_codeAction",
    "elixir_ls.mix_env": "test",
    "elixir_ls.mix_target": "host",
    "elixir_ls.otp_release": "25"
  }
}

Even if I start Zed with RUST_LOG=error zed ., logs continue to accumulate with INFO messages (~) from crates/lsp/src/lsp.rs:304. Is there a way to suppress these messages?

Thank you
