fix: add a missing word in getBytesInUse

[eugenesvk]

Summary

getBytesInUse function was missing a word in a description of its parameters, wrongly implying that passing any array would return a 0 value while in reality only passing an empty array return a 0 value, not any array

Motivation

Avoids confusing the readers on how to use this API

Supporting details

Chrome API description correctly states that

An empty list will return 0.
