custom widget for array fields with no `enums` or `uniqueItems` set to true

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

Why is it not possible to specify a custom widget for array fields with no enums or uniqueItems set to true? I would like to create 2 widgets:

• A multiSelect with the possibility to add new entries (no enum).
• A multiSelect with the possibility to select an entry multiple times (uniqueItems = false).

Steps to Reproduce

1. Having an array without enum or uniqueItems in its items.

const schema = {
  type: "array",
  items: {
    "type": "string"
  },
};

const uiSchema = {
  "ui:widget": "myCustomWidget"
}

Expected behavior

Widget myCustomWidget to be used.

Actual behavior

Widget used is the default rendered by this.renderNormalArray()

Version

Thanks – do you mind adding it to the weekly meeting agenda? I think a synchronous review would be easiest – https://github.com/rjsf-team/react-jsonschema-form/issues/2677

@epicfaace - Not a huge fan of the approach on https://github.com/rjsf-team/react-jsonschema-form/pull/2125 so created https://github.com/rjsf-team/react-jsonschema-form/pull/2697. Would you mind taking a look?
