Prevent File from adding properties into form fields

[darklight9811]

Describe the bug

When we add a field to the form validator, it adds all properties from the file object into the form fields, this really messes up the auto complete and seems unnecessary.

Your minimal, reproducible example

https://stackblitz.com/edit/vitejs-vite-hw3jlbst?file=src%2FApp.tsx

Steps to reproduce

1. create a form
2. add a validation for a file (for example z.file())
3. try to auto complete a field with the name of the file

Expected behavior

Only show the file field itself, not its properties

It'll have to be some solution that can work even if File doesn't exist (since it's browser only and doesn't exist in environments like React Native).

@LeCarbonator do you think filtering the type autocompletion would be enough?
