Deprecate the requests library, use the httpx library

[lighting9999]

It is recommended to deprecate the requests library and use the httpx library to achieve more functionality.
In my #2790, even though it was a draft, these changes were already included:

• Compatible with Python 3.13.5
• Conforms to ruff's syntax and formatting
• Deprecate the requests library in favor of the httpx library
• Use a unified PIP requirements document
