The `perl-binary` classifier now emits `pkg:cpan/perl@<version>` instead of `pkg:generic/perl@<version>`.
`perl` is itself a CPAN distribution and carries advisories under that name, so typing it as `generic` left every one of them unreachable.
This changes an existing purl. Anything keyed on `pkg:generic/perl` (allowlists, policy, SBOM diffs) needs updating.
Builds on the cpan cataloging branch, which adds the package type this uses.
