File not uploading properly
# ISSUE

while uploading file with rest, the type of received file is

```
{
  fieldname: 'file',
  originalname: 'Ellipse 41.png',
  encoding: '7bit',
  mimetype: 'image/png',
  buffer: <Buffer 89  73 00 00 2c 4b 00 00 2c 4b 01 ... 44542 more bytes>,
  size: 44592
}

```
But with graphql-upload, the received file is in the format
```
 {
   filename: 'Ellipse 41.png',
   mimetype: 'image/png',
   encoding: '7bit',
   createReadStream: [Function: createReadStream]
}
```

When I try to create a stream from the file.createReadStream() I get the following error
```
(node:113) [DEP0135] DeprecationWarning: ReadStream.prototype.open() is deprecated
     at ReadStream.open (/home/node/app/node_modules/fs-capacitor/lib/index.js:90:11)
     at WriteStream.<anonymous> (/home/node/app/node_modules/fs-capacitor/lib/index.js:84:49)
     at Object.onceWrapper (node:events:510:26)
     at WriteStream.emit (node:events:402:35)

     at /home/node/app/node_modules/fs-capacitor/lib/index.js:143:14
     at FSReqCallback.oncomplete (node:fs:188:23)
```

So the file uploaded to gcs/s3 or local file system doesn't get written correctly because it's still a stream and not a buffer
it seems like the issue is with fc-capacitor package
