fix: Unable to use "name" as a property in class-validator

[fdorantesm]

Description

Property name is overwritten to "anonymous" if you define a property called "named" in a DTO class.

Minimal code-snippet showcasing the problem

export class UpdateChallengeDto {
  @ApiPropertyOptional({ example: 'April 2024' })
  @IsString()
  @IsDefined()
  public readonly name: string;

  @ApiPropertyOptional({ example: 450 })
  @Min(0)
  @IsOptional()
  @Type(() => Number)
  public readonly price?: number;

  @ApiPropertyOptional({ example: 'f7e7b1e4-9b0b-4b4b-8d2c-6e1f4d4c3d3d' })
  @IsString()
  @IsUUID()
  @IsOptional()
  public readonly playlistId?: string;

  @ApiPropertyOptional({ example: true })
  @IsBoolean()
  @IsOptional()
  @Type(() => Boolean)
  public readonly isActive?: boolean;

  @ApiPropertyOptional({ example: '2024-04-01T00:00:00.000Z' })
  @IsDate()
  @Type(() => Date)
  @IsOptional()
  public readonly startsAt?: Date;

  @ApiPropertyOptional({ example: '2024-04-30T23:59:59.999Z' })
  @IsDate()
  @Type(() => Date)
  @IsOptional()
  public readonly endsAt?: Date;
}

Expected behavior

The classToPlain method will return an object with the original "name" value.

Actual behavior

The classToPlain method is returning the constructor name "anonymous".
