Redundant AWS events declaration

[jfsagasti]

As @NickSeagull pointed out, some cleanup may be possible. We are defining these events in the file-uploaded.ts file:

interface AWSEventS3 {
  s3SchemaVersion: string
  configurationId: string
  bucket: {
    name: string
    ownerIdentity: any
    arn: string
  }
  object: {
    key: string
    size: number
    eTag: string
    sequencer: string
  }
}

interface AWSEvent {
  eventVersion: string
  eventSource: string
  awsRegion: string
  eventTime: string
  eventName: string
  userIdentity: [Record<string, unknown>]
  requestParameters: [Record<string, unknown>]
  responseElements: [Record<string, unknown>]
  s3: AWSEventS3
}

But those events could already be in the AWS SDK, so this re-definition could be unnecessary.
