When we display package manifest and lock files, hyperlink to the upstream package repo web page

When we display a package manifest or lockfile in the resource details, we should have a way to add a hyperlink to the upstream repository web page for this repo: for instance when we browse a requirements.txt lockfile, if it contains: `scancode-toolkit==30.0.1` we should recognize this and link to https://pypi.org/project/scancode-toolkit/30.1.0/

We can parse manifests alright and we can create URLs based on the ScanCode TK packagedcode classes.
