docs: `oxc.fmt.configPath` default

[thernstig]

I am unsure if oxc.fmt.configPath and its default is true or not. The docs say:

| Key                           | Default Value | Possible Values                                                                                               | Description                                                                                                                                                                                                                            |
| ----------------------------- | ------------- | ------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `oxc.fmt.configPath`          | `null`        | `<string>` \| `<null>`                                                                                        | Path to an oxfmt configuration file                                                                                                                                                                                                    |

But what does this mean if I do not set it? Does it not default to finding my config files automatically? I think description should mention if this needs to be set or not.

The confusing part is also that https://oxc.rs/docs/guide/usage/formatter/editors.html has it set:

{
  "oxc.fmt.configPath": ".oxfmtrc.json",
  "editor.defaultFormatter": "oxc.oxc-vscode",
  "editor.formatOnSave": true
}

Is it thus required to be set?

This could use a documentation update.
