[6.15.z] fixing make-docs issue with some update in code

[Satellite-QE]

Cherrypick of PR: #1391

This pull request addresses an issue encountered when generating documentation using Sphinx in the Airgun project. The problem arose due to incompatible type annotations causing errors during the documentation build process.

To resolve this issue, the following changes were made:

• Updated the docstring of the affected module to provide clearer and more descriptive documentation.
• Removed type annotations from the codebase to ensure compatibility

These changes ensure that the documentation build process (make -docs) in Airgun proceeds smoothly without encountering errors related to type annotations.
