When using charp-ts-mode to edit C# files, you often work with generic-types (ie List<string>, etc). csharp-ts-mode has treesitter selectors for this type of syntax, but the current implementation constraints it to only be used in specialized circumstances, when we really want to apply it all over the place.

As an example, generic return-types in function declarations are currently not highlighted correctly.

Attached is a patch which removes this unneeded narrowing of the selector and makes generic types look correct everywhere.

It also corrects a small semantic error (property-use vs variable-use) in initializer-expressions, but I didn't feel like making a separate bug-report for that :)
