Description
When applying the codefix for `CollectionShouldNotContainProperty`, the comparison inside the lambda should also be negated.
```c#
actual.Should().OnlyContain(x => x.OtherProperty == expectedValue); // before
actual.Should().NotContain(x => x.OtherProperty == expectedValue); // after
```

Research direction
Locate the codefix for CollectionShouldNotContainProperty and inspect how it transforms OnlyContain. Reproduce the before/after example, then verify the generated assertion uses NotContain and negates the lambda comparison.
