fix(ffi): fixed create simple logger implementation, removed duplicated word in comment

[aido-mth]

Description

This PR resolves an initialization failure in the FFI tutorial example where create_simple_logger fails to create a logger if the target log file does not already exist.

Currently, the create_simple_logger function hardcodes the overwrite parameter to false when calling SimpleLogger::new. Under the hood, the create_or_open_log_file helper routes false to OpenOptions::new().write(true).append(true).open(log_file). Because it lacks the .create(true) flag, this call returns an error on a fresh run when the file is absent. As a result, the FFI wrapper catches the error, returns 1, and leaves the C-caller without a valid logger instance. From my perspective, current behavior is somewhat counterintuitive for an educational example, as it forces the reader to manually create the file before running the code or figure out why it silently fails.

Proposed Changes

To ensure the example works out-of-the-box:

• Default Flag Adjustment: Changed the hardcoded overwrite argument from false to true inside create_simple_logger. This ensures File::create is called, guaranteeing the file is generated if it doesn't exist.
• Comment Typo Fix: Removed a duplicated preposition (in in real life -> in real life) in the adjacent comment block.
