feat: Add aider translation support

[josix]

This pull request introduces a new script for handling .po files and updates the Makefile to include a new translation target using the aider-chat tool. The most important changes are detailed below:

New Script for .po File Handling:

• .scripts/intercept.py: Added a new script to handle .po files, which includes functionality to parse the file and retrieve specific entries based on their occurrences.

Makefile Enhancements:

• Makefile: Added a new target to install the aider-chat tool in the virtual environment.
• Makefile: Introduced a new translate target that uses the aider-chat tool to translate Python documentation into Traditional Chinese. This target requires FILE and LINE arguments to specify the .po file and the line number to translate.
