`IsEqualTo` is ambiguous when used `new()`

This code generates build error:
```cs
await Assert.That(temporizedValues[0].Value).IsEqualTo(1);
await Assert.That(temporizedValues[0].DateTime).IsEqualTo(new(2023, 01, 02));
```

instead, this works:
```cs
await Assert.That(temporizedValues[0].Value).IsEqualTo(1);
await Assert.That(temporizedValues[0].DateTime).IsEqualTo(new DateTime(2023, 01, 02));
```
