v3.0.0-beta.13 breaks Bubble chart options typings

[santam85]

Declaring the following options:

public bubbleChartOptions: ChartOptions<'bubble'> = {
    scales: {
      x: {
        min: 0,
        max: 30,
        ticks: {}
      },
      y: {
        min: 0,
        max: 30,
        ticks: {}
      },
    }
  };

Throws a type error:

 Property 'scales' is incompatible with index signature.
    Type '{ x: { min: number; max: number; ticks: {}; }; y: { min: number; max: number; ticks: {}; }; }' is not assignable to type 'never'.

Expected Behavior

No error is thrown, the config should be valid

Possible Solution

I believe it's due to EmptyObject in

Chart.js/types/index.esm.d.ts

Line 3187 in 275fdaf

chartOptions: EmptyObject;

type: never takes precedence on the other options? If I use ChartOptions<'bubble'> as a type for the value above, it matches typings correctly, but I need to allow all options.
