Description
Handles outdated versions of the `core/latest-posts` block by converting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.
