Reasoning Agent can execute code now. (#545)

* Enable code execution in reasoning agent

1. enable code execution
2. remove the "verbose" parameter, and replace with AG2's default "silent" parameter.

* init _user_proxy

* notebook update

* notebook update

* add test case for running code in reasoning agent

* use mock credential for reasoning test

* reasoning prompt update

* mock credentials for more tests

* Update .secrets.baseline

* clear notebook outputs

* remove variable F
