fix: ignore underscore throw-away variable

[ekremney]

Description

Underscore variable currently ignored if used as a function argument. I'd like to add an exception to no-unused-vars for the cases where underscore used as a variable name:

const [_, desired] = arr;

Motivation and Context

Stumbled upon a case
