Tests for Word Count pass locally with Ruby 2.6 but fail on Exercism website because test runner is using Ruby 2.5.9

In the Word Count exercise, I'm using to_h with a block, which only becomes available in Ruby 2.6.
https://rubyreferences.github.io/rubychanges/2.6.html#to_h-with-a-block

The error shows for this line in my code:
words.to_h {|word| [word, words.count(word)] }

TypeError: wrong element type String at 0 (expected array)

Traceback (most recent call first):
Line 10:in 'to_h'
Line 10:in 'word_count'

I found the Ruby version by adding this in the code editor:
"ruby #{ RUBY_VERSION }p#{ RUBY_PATCHLEVEL }".frog

NoMethodError: undefined method `frog' for "ruby 2.5.9p229":String

[After that, I discovered there's debug method! 😄 ]

I came here from: https://exercism.org/docs/using/solving-exercises/tests-pass-locally
although I see that the code in this repo already has a .ruby-version of ruby-2.6.6.

I also see that https://github.com/exercism/ruby says

You'll need a recent (2.6+) version of Ruby

So I assume at some point the test runner on the website will be updated to 2.6?
Not sure if this is the right place to report this. Thanks! 😊

Let's see if #41 fixes it :)

I had a similar problem in Bob with the new end-less method definitions.
