[BUG][typescript-axios] string property with date-time format results in string instead of Date

Description

Using typescript-axios generator, I'm getting some undesirable behavior:

For an API with a model property defined as type string with a format of date-time, the generated interface has a type of string instead of Date.

openapi-generator version

@openapitools/openapi-generator-cli: 2.2.6
generator-cli: 5.1.0

OpenAPI declaration file content or url

This yaml

type: object
required:
  - timeSlotId
  - screeningstationId
  - datetime
properties:
  timeSlotId:
    $ref: "../types/id.yaml"
  screeningstationId:
    $ref: "../types/id.yaml"
  datetime:
    type: string
    format: date-time

results in

/**
 * @export
 * @interface TimeSlot
 */
export interface TimeSlot {
    /**
     * @type {number}
     * @memberof TimeSlot
     */
    timeSlotId: number;
    /**
     * @type {number}
     * @memberof TimeSlot
     */
    screeningstationId: number;
    /**
     * @type {string}
     * @memberof TimeSlot
     */
    datetime: string;
}

Generation Details

This is the command used for generation
openapi-generator-cli generate -g typescript-axios -i ..\openapi-spec\openapi.yaml -o .\api

Steps to reproduce

1. Have open api document with above defined property in a schema
2. Generate typescript-axios
3. See output interfaces for undesired results.

This user experienced exactly the behavior that I would assume given my specification. However, he describes it as undesirable behavior. Could it be that the behavior was changed after this issue?
3842 typescript-axios generator string property with date-time format needs to remain a string

Suggest a fix

Add an option to the typescript-axios generator to choose between OpenAPI dates generating variables of datatype string and datatype date in the generated Typescript code.

Start by reproducing the typescript-axios generation with the provided YAML and command, then review related issue 3842 to understand the existing date-time behavior. Done means the generator provides a documented choice between string and Date for OpenAPI date-time properties, with generated interfaces reflecting that choice.
