The ASTNode of `1 <= 2 <= 3` is `to_s`-ed to `(1 <= 2) <= 3`. Right side parenthesis is not required and it causes crystal-lang#4653 error.

Is this getting looked at? @RX14 or @matiasgarciaisaia :) |

This fixes `ToSVisitor` uses parent node information to decide to wrap receiver with parens (so we can detect chained comparison correctly!) `to_s` with `1 <= 2 <= 3` AST yields itself, and now `to_s` with `(1 <= 2).as(Bool)` AST yields itself too.

Fixed #4663
The ASTNode of
1 <= 2 <= 3isto_s-ed to(1 <= 2) <= 3. Right side parenthesis is not required and it causes #4653 error.
