Description

It seems that the PR (#1978) that resolved Issue #2018 has not cascaded down through the existing ruby interface.

I've been experimenting with variations of the `write-file.rb` examples, but passing in the append flag as true (`Arrow::FileOutputStream.open("/tmp/file.arrow", true)`) still results in overwriting the file, and trying the newer interface using truncate and append flags throws `ArgumentError: wrong number of arguments (3 for 2)`.
