Jonas Jenwald 61186698c3 Replace the remaining occurences of instanceof Array with Array.isArray()
*Follow-up to PRs 8864 and 8813.*

As explained in https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray, `instanceof Array` can have inconsistent behavior. To ensure that only `Array.isArray` is used, an ESLint plugin/rule is added to enforce this.
