make `assertRecyclerViewItemCount` accept logical condition instead of exact number

**Description what you'd like to happen:**
cuurently we have `assertRecyclerViewItemCount(id , num)`, what about have ability to be like
`assertRecyclerViewItemCount(id , num > 5 or )` and logical check

Start by finding the existing assertRecyclerViewItemCount(id, num) implementation and its tests. Read how Barista's RecyclerView assertions are structured, then decide how a logical condition would be represented in the public API. Done means callers can assert a condition on the item count rather than only exact equality, with matching tests.
