SA1000 C# 9.0 Target-typed New Expression Spacing

[tscafeFigo]

C# 9.0 has the ability to not require type specification for constructors when the type is known.
https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-9.0/target-typed-new

Currently SA1000 requires a space after the word new.

This new feature should not require spacing and should be added to the following excerpt.
The new keyword is part of a generic type constraint. In this case there should be no space between the new keyword and the opening parenthesis.

Expected Foo foo = new()
Actual Foo foo = new ()
