[BUG][javascript] Missed import of model named File

Bug Report Checklist

There is missing import declaration in Javascript client when I got model called File.

• Have you provided a full/minimal spec to reproduce the issue?
• Have you validated the input using an OpenAPI validator (example)?
• Have you tested with the latest master to confirm the issue still exists?
• Have you searched for related issues/PRs?
• What's the actual output vs expected output?
• [Optional] Sponsorship to speed up the bug fix or feature request (example)

Description

modelNamePrefix option solves this issue but I still consider it as bug. I guess generator thinks that File is reserved Javascript word and doesn't add it to import list.

Generated model(file is pretty big, so I've left only important parts) looks like:

import ApiClient from '../ApiClient';
import CallRecording from './CallRecording';

/**
 * The Greeting model module.
 * @module model/Greeting
 * @version 1.0
 */
class Greeting {

    /**
     * Constructs a <code>Greeting</code> from a plain JavaScript object, optionally creating a new instance.
     * Copies all relevant properties from <code>data</code> to <code>obj</code> if supplied or a new instance if not.
     * @param {Object} data The plain JavaScript object bearing properties of interest.
     * @param {module:model/Greeting} obj Optional instance to populate.
     * @return {module:model/Greeting} The populated <code>Greeting</code> instance.
     */
    static constructFromObject(data, obj) {
        if (data) {
            obj = obj || new Greeting();

            if (data.hasOwnProperty('id')) {
                obj['id'] = ApiClient.convertToType(data['id'], 'Number');
            }
            if (data.hasOwnProperty('type')) {
                obj['type'] = ApiClient.convertToType(data['type'], 'String');
            }
            if (data.hasOwnProperty('text')) {
                obj['text'] = ApiClient.convertToType(data['text'], 'String');
            }
            if (data.hasOwnProperty('call_recording')) {
                obj['call_recording'] = CallRecording.constructFromObject(data['call_recording']);
            }
            if (data.hasOwnProperty('file')) {
                obj['file'] = File.constructFromObject(data['file']);
            }
            if (data.hasOwnProperty('locale')) {
                obj['locale'] = ApiClient.convertToType(data['locale'], 'String');
            }
            if (data.hasOwnProperty('created_at')) {
                obj['created_at'] = ApiClient.convertToType(data['created_at'], 'Date');
            }
            if (data.hasOwnProperty('modified_at')) {
                obj['modified_at'] = ApiClient.convertToType(data['modified_at'], 'Date');
            }
        }
        return obj;
    }

}

And the error is:

[Log] TypeError: File.constructFromObject is not a function. (In 'File.constructFromObject(data['file'])', 'File.constructFromObject' is undefined) — Greeting.js:81 (main.js, line 13027)

Steps to reproduce

Related issues/PRs

#9521 seems related

Suggest a fix

Start with the JavaScript generator configuration and the schema in schema/spec_definition.yml, then inspect the generated Greeting.js output and compare the File model reference with the related issue #9521. Reproduce the missing import using generator version 5.1.1; done means the generated client can call File.constructFromObject without the TypeError.
