Inspired by the idea from the Docker extension for VS Code to add hyperlinks to the base image:

I would love to see a similar feature for the packages listed in a requirements.txt file.

User story:

• When I hover any package name (e.g. setuptools) in a requirements file, it looks like a hyperlink
• When I click this hyperlink, a browser window is opened that redirects me to the relevant pypi.org site (e.g. https://pypi.org/project/setuptools/)

For reference, this is how they implemented it in the Docker extension:
