Fix predictor path synchronization and enhance thread safety

[Shresht7]

This pull request introduces improvements to the PSFavorite module's configuration and initialization, especially around the handling and loading of the favorites file, and adds a new test for predictor initialization. The main changes enhance flexibility in specifying the favorites file path, ensure thread safety when accessing favorites, and improve robustness in file handling.

Configuration and Initialization Improvements:

• Added a FavoritesFile parameter to Initialize-Configuration, allowing customization of the favorites file name (Module/Private/Initialize-Configuration.ps1).
• Changed the logic for constructing the favorites file path to use the customizable file name and ensured the path is set in $Script:FavoritesPath (Module/Private/Initialize-Configuration.ps1).
• On module import, the predictor is now explicitly initialized with the resolved favorites path, ensuring it loads favorites from the correct location (Module/PSFavorite.psm1).

Predictor Implementation Enhancements:

• Refactored PSFavoritePredictor to allow dynamic initialization of the favorites file path, added thread safety for accessing the favorites list, and improved error handling when loading favorites (Predictor/PSFavoritePredictor.cs). [1] [2] [3] [4]

Testing:

• Added a test to verify that initializing the module with a custom favorites path creates the favorites file as expected (Module/Tests/Public/PredictorInitialization.Tests.ps1).
