Getting download_url for a specific older release of Perl

[vadimkantorov]

From https://github.com/metacpan/metacpan-api/blob/master/docs/API-docs.md#download_urlmodule it is not clear if there is a way to retrieve a download_url for a bit older version of Perl. Even if there is no way, it would be good to mention it.

E.g. curl https://fastapi.metacpan.org/v1/download_url/PerlIO::mmap returns https://cpan.metacpan.org/authors/id/P/PE/PEVANS/perl-5.38.2.tar.gz, while https://metacpan.org/release/XSAWYERX/perl-5.32.0/view/ext/PerlIO-mmap/mmap.pm has a link to https://cpan.metacpan.org/authors/id/X/XS/XSAWYERX/perl-5.32.0.tar.gz

Thanks!
