bug(gatsby-source-strapi): When locale: "all" is used in a singleTypes error is thrown on a startup

## Describe the bug
**When locale: "all" is used in a singleTypes error is thrown on a startup:**
```
singleTypes: [
"bottom-banner",
"footer",
{
singularName: "header",
pluginOptions: {
i18n: {
locale: "all",
},
},
queryParams: {
populate: {
logoMobile: "1",
logoDesktop: "1",
headerItem: {
populate: {
dropdown: "*",
}
}
}
}
},
]
```

**Error text:**

```
ERROR #11321 API.NODE.EXECUTION

"gatsby-source-strapi" threw an error while running the sourceNodes lifecycle:

Cannot read properties of undefined (reading 'status')

TypeError: Cannot read properties of undefined (reading 'status')

[frontend_gatsby]/[gatsby-source-strapi]/dist/fetch.js:132:24
```

**I am using strapi v5.6.0, gatsby-source-strapi v5.0.2**

## To Reproduce

1. Add new locale
2. Create a singleType in a Strapi
3. Enable Internalization for this type
4. Create content in multiple locales
5. Add new type gatsby-config.js with ```
pluginOptions: {
i18n: {
locale: "all",
},
},```
6. run gatsby develop

## Expected behavior

No error on startup, graphql request with filter by locale is available
