Add overload to `unshift` to catch calling it with zero elements

lib Update Request

I often mistake unshift for shift; calling array.unshift() with zero arguments is almost always a mistake, and I'd like it to tell me that.

interface Array<T> {
    /**
     * @deprecated You probably meant to use `.shift()`
     */
    unshift(): number;
    /**
     * Inserts new elements at the start of an array, and returns the new length of the array.
     * @param items Elements to insert at the start of the array.
     */
    unshift(...items: T[]): number
}

Configuration Check

My compilation target is ESNext and my lib is the default.

Missing / Incorrect Definition

Array.prototype.unshift

Sample Code

const myArray = ["abc"];

// This should error / warn, as this is almost definitely a mistake
myArray.unshift()

// This should be ok even though the array might have zero elements
myArray.unshift(...myOtherArray)

Issue で特定されている Array.prototype.unshift の標準ライブラリ宣言から始め、近隣のオーバーロードの規約を確認してください。配列メソッドに関する既存の型チェックテストを確認します。引数なしの直接呼び出しがエラーとして報告される一方で、別の配列のスプレッドは引き続き有効であれば完了です。
