* Enhance install script to handle commented and uncommented lines (#3632)

Resolves #3632

Enhance install script to handle commented and uncommented lines in shell file with user prompts for modification.
- Track commented and uncommented lines in the file.
- Prompt user to append or skip if the line is commented.
- Ensure new lines are added only when necessary, based on user input.
- To the `fish_user_key_bindings.fish`, the original logic would append the line to the end if no corresponding statement was found. I’ve adopted the same behavior for commented lines.

* Refactor append_line function to improve line existence check.

- Replaced `lno` variable with `lines` to store matching lines and simplified the logic.
- Improved line existence check, now prints all matching lines directly and handles commented lines separately.
- Removed unnecessary variables like `all_commented`, `commented_lines`, and `non_commented_lines`.

* Fix indentation
