ruby-ts-mode: Highlight more kinds of parameters

* lisp/progmodes/ruby-ts-mode.el
(ruby-ts--font-lock-settings): Highlight destructured parameters,
lambda parameters, identifiers in pattern matching clauses
(array/hash) and exception variables.
Move the 'symbol' matchers lower to make 'hash_key_symbol' lower
priority than hash keys in match patterns.
