Update dependencies in requirements.txt and clean up unused imports

[devanshjainms]

This pull request mainly focuses on cleaning up unused imports and minor code simplifications across both implementation and test files, as well as removing some redundant variables and debugging statements. These changes help make the codebase more maintainable and easier to read.

Code cleanup and simplification

• Removed unused imports such as ipaddress, ABC, abstractmethod, re, shlex, and logging from src/module_utils/collector.py and src/module_utils/filesystem_collector.py to reduce clutter and improve clarity. [1] [2]
• Removed unnecessary imports (unittest.mock, logging, etc.) from several test files to streamline dependencies and encourage the use of pytest for mocking. [1] [2] [3]

Minor logic and test adjustments

• Removed the unused lv_size variable from the LVM details extraction logic in gather_all_filesystem_info for better code clarity.
• Simplified assertions and removed redundant variable assignments in tests, such as eliminating unnecessary result print statements and variable initialization. [1] [2] [3] [4]
