Hooks: add_action() used for use_block_editor_for_post_type filter

[apermo]

Problem

In wp-admin/includes/admin-filters.php at line 88, add_action() is used to register a callback on the use_block_editor_for_post_type hook, but this hook is fired with apply_filters() — making it a filter, not an action.

add_action( 'use_block_editor_for_post_type', '_disable_block_editor_for_navigation_post_type', 10, 2 );

Where the hook fires

• src/wp-includes/post.php:8646 — apply_filters( 'use_block_editor_for_post_type', ... )

The PHPDoc at line 8643 clearly documents this as a filter with @param tags for return value filtering.

Fix

Change add_action() to add_filter().

Confirmed.

https://github.com/WordPress/wordpress-develop/blob/64086b2a15ef4ccf6443de2056646da1ee17d56d/src/wp-admin/includes/post.php#L2626-L2644

_disable_block_editor_for_navigation_post_type() already returns, so a change is not breaking.
