Please describe what the rule should do:

• no-array-prototype-at ... Disallow Array.prototype.at and TypedArray .prototype.at method.
• no-string-prototype-at ... Disallow String.prototype.at method.

These methods will be added in ES2022.

https://github.com/tc39/proposal-relative-indexing-method

Provide 2-3 code examples that this rule will warn about:

var e = array.at(-1);
var e = typedArray.at(-1);
var c = string.at(-1);

Do you think we should rename the rule and to check both arrays and strings?
