Warning CS8620 and CS8619 after update to >= 0.72

[volkmnv]

One CS8620 wanring from here #3394 was fixed in 0.72 but the second one is still there at 'Assert.That(value)'

[Test]
[MethodDataSource(nameof(Data))]
public async Task Test(object? value, object? expected)
{
    await Assert.That(value).IsEqualTo(expected);
}

also an additional CS8619 appeared in this test at 'MethodToTest(data!)':

    [Test]
    [MethodDataSource(nameof(Data))]
    public async Task Test(object? data)
    {
        await Assert.That(() => MethodToTest(data!)).Throws<ArgumentException>();

        Task<object> MethodToTest(object value)
        {
            if (value is null)
                throw new ArgumentNullException(nameof(value));
            return Task.FromResult(new object());
        }
    }
