feat(nestedArray): parsing * on array of array

[raf262]

What this PR does / why we need it: Enable parsing nested arrays.

How does this change affect the cardinality of KSM: (increases, decreases or does not change cardinality)
We can now write this kind of path: "status", "parents", "[*]", "conditions".

Where [*]means listing all the parents object inside the list.

I updated the PR on this day (Jan 16, 2026) to allow the use of [*] at the labelsFromPath & valueFrom. This has been tested on our side and enable us to recover the parentRef name and the condition reason for each condition on HTTPRoute->Status->Parents

Which issue(s) this PR fixes: (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged)
Fixes #2368
