fix: allow for objects inside array metadata to be typed properly

[AmanuelAaron]

Ticket

ET-744

Description

When an object metadata is inside an array, the object elements are now displayable.

Test Plan

Add metadata to a run that has a list of objects (i.e "a": [{"b": 3}, {"c":2}]) then, on the run table select and confirm that the elements are viewable.
