DateTime.now() incorrectly parsing the timezone offset.

Describe the bug When using DateTime.now(), result is being offset twice from the system date applied.

To Reproduce Used Jest to reproduce issue.

1. Mock Sytem Time:

  beforeEach(() => {
    jest.useFakeTimers();
    jest.setSystemTime(new Date("2024-01-15T10:00:00-05:00"));
  });

1. Create a test:

  it('should return date according to the store timezone', () => {
    const result = DateTime.now();
    
    expect(result.toISO()).toBe('2024-01-15T10:00:00.000-05:00');
  });

Actual vs Expected behavior

Actual: '2024-01-15T05:00:00.000-05:00' Expected: '2024-01-15T10:00:00.000-05:00'

It's an issue, as DateTime.utc() correctly calculates UTC time.
