Update tutorial_macros.rst (#5715)

Browse source 
This removes the false statement that Haskell and other functional programming languages does need nor not have macros.

Lisp is a functional programming language with macros at the core of the language. For Haskell specifically its called [Template Haskell](https://wiki.haskell.org/Template_Haskell).

There's also Erlang which has a token based macro system, something between the C preprocessor and Lisp. Elixir, a newer language in the same ecosystem as Erlang, has full procedural macros. This is similar to the macros in Xonsh; regular functions that take AST nodes as input and return a, potentially different, AST node.
