Fix list() and help() torchhub functions for Windows (#63773)

Summary:
This PR Fixes the help() and list() torchhub functions which were probably failing for Windows since the `/` OS separator was hardcoded.

Before merging this I need to double check whether the CI actually runs the corresponding tests on Windows or not
