fix: correct MongoDB ID conversion in hasManyThrough relations

[enes-sahin]

This pull request addresses an issue where MongoDB ID was causing problems in hasManyThrough relations. The solution implemented attempts conversion to a string type using the toString() function for both related and entity IDs. If the toString() function does not exist, the ID is used as it is. This ensures consistency in ID types, allowing the intersection function to work correctly.

Fixes #10259
