* By using the 'theme_json' group, this data is marked to be non-persistent across requests.
* @see `wp_cache_add_non_persistent_groups()`.
*
* The rationale for this is to make sure derived data from theme.json
* is always fresh from the potential modifications done via hooks
* that can use dynamic data (modify the stylesheet depending on some option,
* settings depending on user permissions, etc.).
* See some of the existing hooks to modify theme.json behavior:
* @see https://make.wordpress.org/core/2022/10/10/filters-for-theme-json-data/
*
* A different alternative considered was to invalidate the cache upon certain
* events such as options add/update/delete, user meta, etc.
* It was judged not enough, hence this approach.
* @see https://github.com/WordPress/gutenberg/pull/45372
