json snippets | remove _zip suffix from edition names

[shawnlaffan]

The website requires names like "pdl", not "pdl_zip".

Probably most easily done at this line:

Perl-Dist-Strawberry/lib/Perl/Dist/Strawberry/Step/OutputReleasesJSONSnippet.pm

Line 51 in b672ef3

my @editions = grep {$_ =~ /^(zip|portable_zip|msi|pdl_zip)$/} keys %{$params->{output}};
