[Bug]: xUnit fixer incorrectly converts `Assert.All` with item action

[ascott18]

Description

The following xUnit test will not have the inner item assertions converted.

    [Fact]
    public void TestWithAssertAll()
    {
        var items = new[] { 1, 2, 3 };

        Assert.All(items, item =>
        {
            Assert.True(item > 0);
            Assert.True(item < 10);
            Assert.NotEqual(0, item);
        });
    }

Expected Behavior

Ideally, an overload of All that takes an async delegate and allows for nested awaited TUnit assertions, perhaps working in a similar way for Assert.Multiple() for each nested item? Like this:

        await Assert.That(items).All(async item =>
        {
            await Assert.That(item > 0).IsTrue();
            await Assert.That(item < 10).IsTrue();
            await Assert.That(item).IsNotEqualTo(0);
        });

Or, failing that, to just have the assertion be converted to a foreach loop:

        foreach (var item in items)
        {
            await Assert.That(item > 0).IsTrue();
            await Assert.That(item < 10).IsTrue();
            await Assert.That(item).IsNotEqualTo(0);
        };

Actual Behavior

Fixer produces the following, which is not a valid way to use TUnit's All assertion, and inner assertions are left as xUnit assertions.

        await Assert.That(items).All(item =>
        {
            Assert.True(item > 0);
            Assert.True(item < 10);
            Assert.NotEqual(0, item);
        });
