#### What are you trying to achieve or the steps to reproduce?

By using `server.register(pluginArray)`, typescript does not work.
Registering the same plugins one by one, it works.

```js
import { Server, Plugin } from '@hapi/hapi';

interface TestPluginOptions {
x: number;
}

interface TestPluginDecorations {
plugins: {
test: {
add(a: number, b: number): number;
};
}
}

const plugin1: Plugin = {
name: 'test',
version: '1.0.0',
register: function (srv, options) { }
};

const plugin2: Plugin<{}> = {
name: 'tes2',
version: '1.0.0',
register: function (srvs, options) { }
};

const plugin3: Plugin = {
name: 'tes2',
version: '1.0.0',
register: function (srvs, options) { }
};

async function test() {
const server = new Server();

// does not work
await server.register([
{ plugin: plugin1, options: { x: 1 } },
{ plugin: plugin2, options: {} },
{ plugin: plugin3, options: undefined },
]);

// works
await server.register({ plugin: plugin1, options: { x: 1 } });
await server.register({ plugin: plugin2, options: {} });
await server.register({ plugin: plugin3, options: undefined });
}

test()
```

#### What was the result you got?

```
Type '{ x: number; }' is not assignable to type 'void'.
```

#### What result did you expect?

It should work with `tsc index.ts`
