Support C# 12 collection expressions

[meenzen]

C# 12 Collection expressions can't be formatted yet.

Example:

public class FooBar
{
    public void Foo()
    {
        List<string> list = ["Foo", "Bar"];
        Print(list);
    }

    public void Bar()
    {
        string[] array = ["Foo", "Bar"];
        Print(array);
    }

    private static void Print(IEnumerable<string> strings)
    {
        foreach (string str in strings)
        {
            Console.WriteLine(str);
        }
    }
}

Errors:

FooBar.cs - Failed to compile so was not formatted.
