PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Remove duplicate version specification to prevent version ambiguity Remove the duplicate '3.1.6' line from the .ruby-version file as it creates ambiguity about which version should be used. rb/.ruby-version [1-2] +3.2.2 - 3.1.6 Apply this suggestion Suggestion importance[1-10]: 9 Why: Having two different Ruby versions (3.2.2 and 3.1.6) in the .ruby-version file is a critical issue that could cause version conflicts and inconsistent behavior across different environments. The duplicate line should be removed to maintain a single, clear version specification.	9
