onDrop should use File[] instead of any[] for acceptedFiles parameter

[hkiame]

Currently, the onDrop function in vue3-dropzone has the following type signature:

onDrop: (acceptedFiles: any[], rejectReasons: FileRejectReason[], event: Event) => void

This ensures:

• Better Type Safety - Ensures only valid File objects are processed.
• Improved DX (Developer Experience) - TypeScript will properly infer properties on acceptedFiles without requiring manual type casting.
• Consistency - The parameter is supposed to represent accepted files, and files in JavaScript are represented as File objects.
