Create a refactoring for asserting exceptions properties

for example:

```cs
public class MyCustomException : Exception
{
public string MyCustomProperty { get; }

public MyCustomException(string myCustomProperty)
{
MyCustomProperty = MyCustomProperty;
}
}
```

when hovering over the property `MyCustomProperty` I would like to have a suggestion to generate an assertion for that property.

The generated assertion will something like this:
```cs
public static class MyCustomExceptionExtensions
{
public static ExceptionAssertions WithMyCustomProperty(this ExceptionAssertions assertions,
string expectedMyCustomProperty, string because = "", params object[] becauseArgs) where TException : MyCustomException
{
Execute.Assertion
.ForCondition(assertions.And.MyCustomProperty.Equals(expectedMyCustomProperty))
.BecauseOf(because, becauseArgs)
.FailWith("Expected exception with MyCustomProperty {0}{reason}, but found {1}.", assertions.And.MyCustomProperty, expectedMyCustomProperty);
return assertions;
}
}
```

No files, tests, or entry points are named in the issue, so first locate the analyzer's refactoring implementations and their tests. Use the requested C# exception-property example to define the generated assertion and verify that hovering over a property offers the refactoring with the expected output.
