Codex:

Handles outdated versions of the `core/latest-posts` block by converting attribute `categories` from a numeric string to an array with key `id`.

This is done to accommodate the changes introduced in #20781 that sought to add support for multiple categories to the block. However, given that this block is dynamic, the usual provisions for block migration are insufficient, as they only act when a block is loaded in the editor. TODO: Remove when and if the bottom client-side deprecation for this block is removed.
