Type error setting pointStype to false

### Expected behavior

I hope I can define a dataset with a boolean pointStyle without getting a typing error

### Current behavior

When i add the following config:

```typescript
new Chart(canvas, {
type: 'line',
data: {
labels: generateLabels(),
datasets: [
{
label: 'Dataset',
data: generateData(),
pointStyle: false, <--
},
],
}
```

I get the following typing error

_Type '{ pointStyle: boolean; }' is not assignable to type 'ChartDatasetCustomTypesPerDataset<"line", number[]>'._

### Reproducible sample

Updated example: https://codesandbox.io/s/ng2charts-chart-js-issue-template-forked-6fd62d?file=/src/app/app.component.ts

(does not complain about the boolean type, but neither does it complain about an invalid string type)

### Optional extra steps/info to reproduce

_No response_

### Possible solution

It is currently "fixed" by forcing a type as shown here

`pointStyle: false as unknown as string,`

but I wouldn't want to have to do this.

### Context

I am working on Angular 16

### chart.js version

4.3.0

### Browser name and version

Firefox Developer Edition 115.0b9 (64-bit) on Ubuntu

从 Chart.js 的折线图 TypeScript dataset 配置开始，追踪 pointStyle 属性声明的类型。使用更新后的 CodeSandbox 验证 false 会被接受，而无效字符串仍会被拒绝；在不使用 workaround 的情况下解决报告的类型错误即表示完成。
