biome-vscode: Extension 'Biome' is configured as formatter but it cannot format 'JavaScript'-Files

When i click configure, no biome is in the list.

I created a fresh new example project:

Installed Biome v2.0.0 in VSCode.

Added settings.json

  "[javascript]": {
    "editor.defaultFormatter": "biomejs.biome"
  },
  "editor.formatOnSave": true,

/example.code.workspace

{
  "folders": [
    {
      "path": "biome-test"
    }
  ]
}

/biome-test/package.json

{
  "name": "biome-test",
  "version": "1.0.0",
  "main": "index.js",
  "devDependencies": {
    "@biomejs/biome": "^1.4.1"
  }
}

/biome-test/biome.json (from biome-hompeage

{
  "$schema": "https://biomejs.dev/schemas/1.4.0/schema.json",
  "organizeImports": {
    "enabled": false
  },
  "linter": {
    "enabled": true,
    "rules": {
      "recommended": true
    }
  }
}

/biome-test/index.js

console.log("Hello World!") // without semicolon so `biome check index.js` errors in cli

Restart everything, vscode has no biome.

In command line i can execute:

cd biome-test
./node_modules/.bin/biome check index.js

It shows Checked 1 file(s) in 1031µs Found 2 error(s)

Adding /biome/test/biome.json

  "javascript": {
    "formatter": {
      "semicolons": "asNeeded"
    }
  }

Re-run and it shows Checked 1 file(s) in 932µs

So biome cli works and uses biome.json.

But not in VSCode. Tried nightly too, the same, no biome detected.

VSCode 1.84.2 Biome v2.0.0 Node v18.19.0 Linux Mint 21.2 (Ubuntu jammy)

Let me know, if i can provide more informations.
