Save the permalinks structure after changing custom post types

[igorschoester]

Describe the feature you'd like

When the setting Enable post types & taxonomies. is changed, also update the permalink structure in WordPress, preventing 404s in the docker environment.

Reproduce

1. Disable Enable post types & taxonomies..
2. Save the WP permalink settings.
3. Enable Enable post types & taxonomies..
4. Go to a frontend page of a book for example and see a 404 page. Tip, use the sitemap: http:https://basic.wordpress.test/book-sitemap.xml

The workaround is manually saving the permalink settings again.
