Add a component parameter with an overridden base property without the parameter attribute throws ArgumentException

[nickmuller]

Describe the bug or question
Add a component parameter with a component property which overrides an abstract property of an abstract class without the parameter attribute throws ArgumentException.

With this test:

public class BoolFieldTest : TestContext
{
    [Fact]
    public void Test()
    {
        RenderComponent<BoolField>(parameters => parameters
            .Add(x => x.Value, null));
    }

    public class BoolField : BaseFieldComponent<bool?>
    {
        [Parameter] public override bool? Value { get; set; }
    }

    public abstract class BaseFieldComponent<T> : ComponentBase
    {
        public abstract T Value { get; set; }
    }
}

Results in this output:

System.ArgumentException
The parameter selector 'x => x.Value' does not resolve to a public property on the component 'BoolFieldTest+BoolField' with a [Parameter] or [CascadingParameter] attribute.
   at Bunit.ComponentParameterCollectionBuilder`1.GetParameterInfo[TValue](Expression`1 parameterSelector) in /_/src/bunit.core/ComponentParameterCollectionBuilder.cs:line 355
   at Bunit.ComponentParameterCollectionBuilder`1.Add[TValue](Expression`1 parameterSelector, TValue value) in /_/src/bunit.core/ComponentParameterCollectionBuilder.cs:line 55

Expected behavior:
I would expect this to work. As a workaround I now set the [Parameter] attribute on the abstract property.

Hey @nickmuller

Thanks for reporting this. That is indeed a bug, and I will push a fix later that solves it. It should be available as a nightly build after that, if you are blocked: #209
