docs: Query tensor store for a given debugged tensor value.
  
      Args:
        watch_key: The watch key of the debugged tensor being sought. Format:
          <node_name>:<output_slot>:<debug_op>
          E.g., Dense_1/MatMul:0:DebugIdentity.
        time_indices: Optional time indices string By default, the lastest time
          index ('-1') is returned.
        slicing: Optional slicing string.
        mapping: Optional mapping string, e.g., 'image/png'.
  
      Returns:
        If mapping is `None`, the possibly sliced values as a nested list of
          values or its mapped format. A `list` of nested `list` of values,
        If mapping is not `None`, the format of the return value will depend on
          the mapping.
