docs-bug(datepicker): Wrong docs for parsing dates as UTC with luxon

### Documentation Feedback

The docs include this extract:

> By default the LuxonDateAdapter creates dates in your time zone specific locale. You can change the default behaviour to parse dates as UTC by passing useUtc: true into provideLuxonDateAdapter:
>
> ```ts
> bootstrapApplication(MyApp, {
> providers: [provideLuxonDateAdapter(undefined, {useUtc: true})]
> });
> ```

[`provideLuxonDateAdapter()` only takes the 1 parameter](https://github.com/angular/components/blob/46b67d15053ce31b4742b809f1777b32eb2f1863/src/material-luxon-adapter/adapter/index.ts#L32-L34), no second `options` with `useUtc`.

My guess is this is a holdover from Moment, which does have this option.
It would be nice, and fairly easy, to actually have this same option.
edit: I went ahead and [made a PR](https://github.com/angular/components/pull/32936) copying the Moment adapter.

The current actual way to achieve it is:
```ts
bootstrapApplication(MyApp, {
providers: [
provideLuxonDateAdapter(),
{
provide: MAT_LUXON_DATE_ADAPTER_OPTIONS,
useValue: {
useUtc: true,
} satisfies Partial,
},
]
});
```

打开受影响的 datepicker 概览页面，并将其中的 LuxonDateAdapter 示例与链接到的适配器源代码 src/material-luxon-adapter/adapter/index.ts 进行比较。查看现有的 PR，并更新文档，使所描述的配置与受支持的 API 相匹配，并确保文档中记录的 UTC 设置准确无误。
