Trouble trying to create a Tileset Source.

Nobody has claimed this yet.

Hi !

I'm trying to use the [createTilesetSource ](https://github.com/mapbox/mapbox-sdk-js/blob/main/docs/services.md#createtilesetsource) function in the services section, and it returns me an error:

`No file data in request. Expected 1 file named "file".`

I'm using it like that :

```javascript
import MapboxTilesets from "@mapbox/mapbox-sdk/services/tilesets";
const tilesetsClient = MapboxTilesets({ accessToken });
```
and
```javascript
async CreateTilesetSource() {
console.log("Create A Tileset Source");

const tilesetId = "newTileSet";

const data = await this.GetJsonFile();
const geoJsonData = GeoJson.parse(data, { Point: ["lat", "lng"] });
const blobFile = new Blob([geoJsonData], { type: "application/json" });

return new Promise((resolve) => {
tilesetsClient
.createTilesetSource({
id: tilesetId,
file: blobFile,
})
.send()
.then((res) => {
const tilesetSource = res.body;
console.log(tilesetSource);
})
.catch((res) => {
console.log("--- CATCH ERROR ! ---");
console.log(res.message);
resolve(null);
})
.done();
});
}
```

Thank you in advance ! : )

Start with docs/services.md at the createTilesetSource entry and reproduce the supplied browser example using a Blob. Inspect how createTilesetSource handles the file argument and compare that with the request's expected file field. Done means the reported example either succeeds or the required input and limitation are clearly documented.
