Describe the Bug

When using the Starlight plugin, specifically the starlight-sidebar-topics-dropdown-plugin, users may encounter an error message indicating an invalid config update. This issue arises due to a mismatch between the expected config type and the actual config provided. The expected type is a specific object structure, whereas the provided config contains an i18n label object, which is not recognized by the plugin.

Error Message

The error message displayed is:

[AstroUserError] Invalid config update provided by the 'starlight-sidebar-topps-dropdown-plugin' plugin

Expected Config Type

The expected config type is defined as:

{
  label: string; link: string;  } | { label: string; items: array; } | { label: string } | { label: string; slug: string } | string

Provided Config

The provided config item contains an i18n label object:

{
  label: {
    en: "thing",
    // wanted to add more but even without extra items it still errors
  },
  autogenerate: { directory: "path/" },
},

Documentation

The current documentation for the Starlight plugin suggests that using an i18n label object is a valid configuration option. However, it appears that there may have been a recent change that has broken this functionality.

Expected Behavior

A valid config should be created for multilingual sites, allowing users to easily manage their content across different languages.
