Ruby translation: openOrSenior is a bad method name. Rename it to: open_or_senior

Ruby method name should be snake case get_count instead of getCount

Please, check the kata test cases (for ruby)!

squareSum([1, 2])
#=> 3
Test Passed

squareSum([1, 2])
#=> 3
Value is not what was expected

Suggestion for ruby-kata.

Change method name from this: keysAndValues(data)

into this: keys_and_values(data)
