Using user's query in configs search might result in loosing some configs. Imagine user filter documents based on their path or title.

What if we use first retrieved content to get the locale and use it in configs query?

const dirConfigs = await serverQueryContent(event, contents.length ? { _locale: contents[0]._length } : {})
    .where({ _path: /\/_dir$/i, _partial: true })
    .find()
