Running `composer dump-autoload` causes a PHP Fatal error

[ntwb]

Steps to reproduce:

1. On a clean Altis v8 install add a custom module with an entry point file based on loading custom module docs here
2. Run composer dump-autoload
3. Open https://subdomain.altis.dev/wp-admin/

Reproduced on both ARM64 & Intel Mac installs of the same project.

Site does not load and the following PHP Fatal is displayed:

Fatal error: Uncaught Error: Class 'Yoast\WP\Duplicate_Post\Admin\Options_Page' not found in /usr/src/app/vendor/yoast/duplicate-post/duplicate-post-options.php:21

Acceptance criteria:

• [x] Custom module entrypoints are loaded
• [x] composer dump-autoload runs without error
• [x] Site does not produce a fatal error

As far as I can tell running composer dump-autoload ends up skipping all 2nd level dependencies that are not the standard type e.g. wordpress-plugin or wordpress-muplugin.

As a temporary work around you can use composer install to regenerate autoload files for now.
