Fix: Allow Disabling System Proxy in Requests

[dosine-staging]

This pull request addresses the issue where the requests library in a Windows environment was unable to bypass the system proxy settings when using PyCharm and JupyterLab. The problem was that setting proxies to None, {}, or "" did not prevent the use of the system proxy.

Changes Made:

• Modified the merge_environment_settings method in sessions.py to ensure that when proxies is explicitly set to None, the environment proxies are not automatically applied.

Impact:

• Users can now effectively bypass the system proxy by setting proxies to None, {}, or "" in their requests, allowing direct internet access without using the system proxy.

This fix resolves the issue reported in Task ID: I_kwDOABTKOs6UWlu5, ensuring that the requests library behaves as expected when users wish to disable proxy usage.
