ruby-ts-mode: Rehash which nodes should be treated as sexps

* lisp/progmodes/ruby-ts-mode.el (ruby-ts-mode): Recognize smaller
syntactic elements as sexps too (bug#62416).  Also do that for
heredocs, regexps and symbol arrays.  But drop binary expressions
(including assignments) since they led to non-intuitive behavior.
