chore: Add Visual Studio Code debug and settings configurations (#57)

This change introduces Visual Studio Code configuration files and
updates a test case:

1. Added `.vscode/launch.json`:
   - Configured a debug configuration for the Analyser module
   - Set up environment variables for debugging

2. Added `.vscode/settings.json`:
   - Configured Python testing settings for pytest
   - Set up file exclusions for cache directories

3. Updated `test_repository_analysis.py`:
- Changed the `path_to_repo` variable from "test" to "tester" in the
`test_analyse_repository` function

These changes improve the development environment setup and slightly
modify a test case.
