Regression in ruby 3.2-rc: vendor/ruby/3.2.0+2/gems/liquid-4.0.3/lib/liquid/variable.rb:124:in taint_check': undefined method tainted?' for "Access Token":String (NoMethodError)

While updating some CI builds using jekyll to use ruby:3.2-rc docker image, I caught this error:

/vendor/ruby/3.2.0+2/gems/liquid-4.0.3/lib/liquid/variable.rb:124:in `taint_check': undefined method `tainted?' for "Access Token":String (NoMethodError)
      return unless obj.tainted?
                       ^^^^^^^^^
	from /vendor/ruby/3.2.0+2/gems/liquid-4.0.3/lib/liquid/variable.rb:89:in `render'

	from /vendor/ruby/3.2.0+2/gems/jekyll-4.2.2/lib/jekyll/liquid_renderer/file.rb:39:in `block (3 levels) in render!'

I think the method is to be removeed in ruby 3.2 .
