[docs] Fix missing Persistence page (#2828)

Fixes #2826, extracted from #2680 

The problem is that we had two different articles whose ids were being
derived as `persistence`, the `persistence.mdx` file and the
`persistence/` example.

I've

1. Made it an error for two articles to have the same id
2. Renamed the `persistence/` article to `local-storage` since that's
the API it's using.
