Array.at() passing ES5 check

[christowiz]

Requested Update

es-check is failing when testing array.at() which is an ES2022. I created a ticket in the acorn repo but was told it's not a syntax problem (which in hindsight it isn't).

acornjs/acorn#1335

var arr = [1, 2, 3];
var lastVal = arr.at(-1);

console.log('lastVal:', lastVal);

Run npm run es-check to validate file
