Support top-level array in JSON files

Is your feature request related to a problem? Please describe

When working on SEO, there are many instances where creating a single JSON array file is MUCh more convenient than having hundreds of small files, especially when working with AI.
If I want to change something to all my content, I would either have to manually change files one by one, or ask Cursor to go through every file and edit it, which is much more expensive AND complex than editing a single file

Describe the solution you'd like

Simply being able to have one single JSON file for all my documents.

Describe alternatives you've considered

I tried creating a collection with a sub-property array, but it does not support large arrays, after 96 or so I get an error (does not seems related to the length but more the size of the file. I made some tests and it seems like 59kb is the size after which it crashes, with syntax error near "collectionName", no matter what the syntax is)

Have you tried creating a custom source for your collection? https://content.nuxt.com/docs/advanced/custom-source
Your goal is very similar to the custom source example in the docs.
