Fix Typo in Documentation and Improve Iterator Comment Clarity

[kilavvy]

Description:
This pull request addresses two minor issues:

1. Fixes a typo in the documentation file docs/src/relationship-particles.md by correcting "specfic" to "specific".
2. Improves the comment in utils/src/iterators.rs for better clarity by changing "clonable" to "cloneable".

These changes enhance the accuracy and readability of both the documentation and code comments. No functional code changes are included.
