How to make BreadcrumbList with multiple breadcrumb trails

According to the Google docs [here](https://developers.google.com/search/docs/appearance/structured-data/breadcrumb#html_example) it should be possible to have multiple BreadcrumbList items in an array inside the script tag. However, this doesn't seem possible with react-schemaorg since you cannot pass an array of objects to jsonLdScriptProps() you can only pass a single object.

What I would like to do is:
```
const data = jsonLdScriptProps(
[{
"@context": "https://schema.org",
"@type": "BreadcrumbList",
"@id": "/#breadcrumlist",
itemListElement: [
{
"@type": "ListItem",
position: 1,
name: "Articles",
item: "https://example.com/",
},
{
"@type": "ListItem",
position: 2,
name: "Archive",
item: `https://example.com/a/${utcYear}/${utcMonth}/`,
},
],
},
{
"@context": "https://schema.org",
"@type": "BreadcrumbList",
"@id": "/#breadcrumlist",
itemListElement: [
{
"@type": "ListItem",
position: 1,
name: "Home",
item: "https://example.com/",
},
{
"@type": "ListItem",
position: 2,
name: `${section}`,
item: `https://example.com/sections/${section}/`,
},
],
},
);
```
But this generates an error:
```
Type 'BreadcrumbListLeaf[]' does not satisfy the constraint 'Thing'.
Property '"@type"' is missing in type 'BreadcrumbListLeaf[]' but required in type 'TouristDestinationLeaf'.ts(2344)
```

jsonLdScriptProps() の型シグネチャから始めて、その入力がどのように表現され、レンダリングされるかを追跡します。既存の単一オブジェクトの動作を維持したまま BreadcrumbList[] を受け入れられるかを判断し、その結果の JSON-LD に要求された複数のパンくずリストの経路が含まれていることを確認します。
