The FieldValidation type doesn't support objects in schemas

[Steffan-Ennis]

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

In index.d.ts the FieldValidation type does not support the schemas that have properties of type: 'object' with there
own properties keys

Steps to Reproduce

For the following schema

import * as RJSF from '@rjsf/core'

const mySchema = {
  'type': 'object',
  'properties': {
    'anotherObject': {
      'type': 'object',
      'properties': {
        'someField': {'type':'string'}
      }
    }
  }
}

function customValidate(formData:any, errors:RJSF.FormValidation):RJSF.FormValidation {
  if(!formData.anotherObject.someField){
    errors.anotherObject.someField.addError('This field has special validation rules')
  }

  return errors
}

Expected behaviour

Typescript should compile

Actual behaviour

There are typescript compilation errors
