Remove trailing whitespace from comments and update test output

[davispuh]

This PR removes trailing whitespace for created comments.
Previously it was # @return [Integer] (with at the end). This removes that.
After applying #9 #10 I've updated test outputs aswell. Not sure how good idea is to commit those but that's how it's been done before.

Pull request overview

This PR removes trailing whitespace from generated comments in the FFI generator output. Previously, comments like # @return [Integer] (with a trailing space) are now generated as # @return [Integer] (without the trailing space). The changes also update test output files to reflect the corrected formatting after applying related PRs #9 and #10.

Changes:

• Modified the write_array method in the Writer class to conditionally add spacing between prefixes and entries
