DateFormatter prints extra dash "-" for negative date times

[thejoecode]

Describe the bug

Version 19, .net Core 7
Date times such as: DateTimeOffset.Parse("2022-09-25T17:59:59-07:00")
Get saved to diff file as: 2022-09-25 18:00 --7

A clear and concise description of what you expected to happen:
Ideally the result would be: 2022-09-25 18:00 -7

Add any other context about the problem here.
Issue is in: src/Verify/Serialization/DateFormatter.cs

GetDateOffset adds a dash "-" to the front of the negative number 7.
For some reason offsetMinutes will also be negative for the offset minute case:
DateTimeOffset.Parse("2022-09-25T17:59:59-07:30") => --7--30

static string GetDateOffset(DateTimeOffset value)
{
    var offset = value.Offset;

    if (offset > TimeSpan.Zero)
    {
        if (offset.Minutes == 0)
        {
            return $"+{offset.TotalHours:0}";
        }

        return $"+{offset.Hours:0}-{offset.Minutes:00}";
    }

    if (offset < TimeSpan.Zero)
    {
        if (offset.Minutes == 0)
        {
            return $"-{offset.Hours:0}";
        }

        return $"-{offset.Hours:0}-{offset.Minutes):00}";
    }

    return "+0";
}

Minimal Repro

  [Fact]
  public async Task DateTest() {
    var dto = DateTimeOffset.Parse("2022-09-25T17:59:59-07:30");

    await Verify(dto)
      .DontScrubDateTimes();
  }
