ErrorSchema is a none deterministic type thus can't be used to accurately type Field components

[Steffan-Ennis]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

What theme are you using?

core

Version

4.1.1

Current Behavior

The type ErrorSchema is non deterministic

import { ErrorSchema } from '@rjsf/core'

const errorSchema: ErrorSchema = {
  __errors: [
    'This field is required'
  ]
}

raises the following compile error
Type 'string' is not assignable to type 'ErrorSchema'

Expected Behavior

The ErrorSchema type should be deterministic so it's usable when typing field components and testing those types
