Biome: Set config to root, remove config path

When root is true, and a config-path is set, biome errors out, which is why I had set root to false.

  ✖ Found a nested root configuration, but there's already a root configuration.
  
  ℹ The other configuration was found in .
  
  ℹ Use the migration command from the root of the project to update the configuration.

Something changed in a recent version causing this, but I can't pin it down.
Since we use the default config path anyway, there's no reason to specify a path, and at least from my testing, this make biome work as expected in vscode and zed.
