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,
},
]
});
```

### Affected documentation page

https://material.angular.dev/components/datepicker/overview#choosing-a-date-implementation-and-date-format-settings

影響を受ける datepicker の概要ページを開き、そこにある LuxonDateAdapter の例を、リンク先の src/material-luxon-adapter/adapter/index.ts にある adapter のソースと比較します。既存の PR を確認し、説明されている構成がサポート対象の API と一致し、文書化されている UTC の設定が正確になるようにドキュメントを更新します。
