[Bug Report][3.6.13] v-file-input rules uses Array value even when multiple prop is false or not specified

[Paul-DS]

Environment

Vuetify Version: 3.6.13
Vue Version: 3.4.27
Browsers: Chrome 127.0.0.0
OS: Linux x86_64

Steps to reproduce

Create a v-file-input without multiple property. Add a validation rule.

Expected Behavior

The value passed to validation rules should be a File or null (to be consistent with the model value)

Actual Behavior

The value passed to validation rules is an array

Other comments

I suppose #17687 fixed the same behavior on the model, but not on the rules

Hi, I already work on this issue and will raise PR later.

The model is still returning an empty array even though no multiple is specified (3.7.2).
