Passing a single-element array to `Promise.all()`, `Promise.any()`, or `Promise.race()` is likely a mistake.

## Examples

```js
// ❌
const foo = await Promise.all([promise]);

// ❌
const foo = await Promise.any([promise]);

// ❌
const foo = await Promise.race([promise]);

// ✅
const foo = await promise;
```

```js
// ❌
const promise = Promise.all([nonPromise]);

// ✅
const promise = Promise.resolve(nonPromise);
```

```js
// ✅
const foo = await Promise.all(promises);
```

```js
// ✅
const foo = await Promise.any([promise, anotherPromise]);
```

```js
// ✅
const [{value: foo, reason: error}] = await Promise.allSettled([promise]);
```
