In Ruby 3.4.7 there is a waring:

warning: literal string will be frozen in the future (run with --debug-frozen-string-literal for more information)

This PR removes that warning by adding string elements to an array and then join them afterwards, this also has a performance benefic as the runtime does not need to reserve new memory on each iteration for the string resulting of concatenating the previous string with the new value.
