Description

All nullable arrays are generated as non-nullable in the javascript proxy.

Welcome to a new episode of proxy generation bugs ;-) Given the abundant bugs in this area, IMHO the abp team should throughly review the proxy generation system.

Reproduction Steps
public class MyDto {
  public int[]? IntArray { get; set; }
  public string[]? StringArray { get; set; }
}
> abp help     
ABP CLI 9.2.0-rc.2
> abp generate-proxy -t ng --entry-point .
export interface MyDto {
  intArray: number[];  // should be nullable
  stringArray: number[];  // should be nullable
}
Expected behavior

Generate properties with correct nullablility.

Actual behavior

All nullable array properties are generated as non-nullable.

Regression?

Possibly.
