Added timeout on request.get() for ensuring that if a recipient serve…
We have detected this issue in the `main` branch of `pandas` project on the version with commit hash `f0814b`. This is an instance of an api usage issue.

**Fixes for api usage issues:**
In file: `web/pandas_web.py`, in method `roadmap_pdeps`, `home_add_releases` and `maintainers_add_info` a request is made without a timeout parameter. If the recipient server is unavailable to service the request, [application making the request may stall indefinitely. ](https://docs.python-requests.org/en/master/user/advanced/#timeouts)our intelligent code repair system **iCR** suggested that a timeout value should be specified.

This issue was detected by our **OpenRefactory's Intelligent Code Repair (iCR)**. We are running **iCR** on libraries in the `PyPI` repository to identify issues and fix them. You will get more info at: [pypi.openrefactory.com](https://pypi.openrefactory.com/)
