SA1118 false positive with multi-line collection expressions as arguments

[ecampidoglio]

Passing a multi-line collection expression as argument in C# 12 triggers SA1118:

// ⚠️ SA1118 The parameter spans multiple lines
foo.Bar(
    [
        "foo",
        "bar",
        "baz"
    ]);

Specifying the elements on the same line does not trigger the warning:

foo.Bar(["foo", "bar", "baz"]);

This is on version 1.2.0-beta.507.

There is currently no way of adding tests for c# 12 constructs in this repository, so this will have to wait for a while. It should be trivial to fix once that is in place, though.

Side note: Based on the analyzer code, I understand that this should happen, but it doesn't for me. I actually can't get SA1118 to trigger on anything. So weird. Would be interesting to hear if anyone else is having the same problem as me. Otherwise I assume that something is wrong with my computer.
