fix: report on child keys when using pattern or notPattern assertions

[tatomyr]

What/Why/How?

When introspecting objects with pattern and notPattern assertions, Redocly CLI highlights the parent key:

paths: # <- highlighted
   correct: ...
   wrong: ...

This changes the report location to children keys:

paths: 
   correct: ...
   wrong: # <- highlighted
