whyisjake f2d1e16f50 Posts, Post Types: Don't add a trailing number when there is a unique post parent. ...

WordPress tries to avoid an issue where slugs might match an existing slug of a page/post. 
If we are in a hierarchical post type, there will be a level, and we can leave it the same.

Fixes #51147.
