🌐 Added Support for the Bangla Language

This pull request introduces support for the Bangla language within the project. Given the linguistic similarity between Bangla and Hindi, where both languages share a common origin and similar sentence structures, this implementation involved leveraging the existing Hindi class as a template and adapting it for the Bangla language.

Changes Made:

• Created a new class for the Bangla language by duplicating the existing Hindi class.
• Added the class in languages.py
