Optimize PyTorch URL extraction: only parse for selected GPU type

Browse Source 
Instead of extracting all three GPU URLs unconditionally, now only
extracts the URL for the user's selected GPU type. More efficient:
- Only one grep execution instead of three
- Less code duplication
- Faster execution
