Thanks, this definitely is an improvement since it handles all mentioned cases.

However, there are still a lot of more things that need fixing.
When point is on the left curly bracket in

  b = %Q{This is a "string"}

'C-M-f' doesn't move to the right curly bracket.
Also double quotes inside the string are not matched by 'C-M-f'.

In

  d = %(hello (nested) world)

'C-M-f' doesn't move to the closing parens from opening parens.

Looking at test/lisp/progmodes/ruby-mode-resources/ruby.rb
for example here curly brackets are not matched with 'C-M-f C-M-b'
in string interpolation and regexps:

  "abc/#{ddf}ghi"

  /foo/xi != %r{bar}mo.tee

Do you think it is possible to handle these cases
by crafting treesit-sexp-type-regexp?
