feat(zig): multiline

[uchars]

I could not find any example for LoopType- and IfTypeExpr, and i do not understand enough about treesitter to write them using the tree-sitter-zig code.
The TypeExpr would essentially just be

(LoopTypeExpr
  (_ (_TypeExpr (_) @context.end))
) @context

but i am not really sure if doing something like

(LoopTypeExpr
  (_ (_ (_) @context.end))
) @context

is a good idea.
