Bug#923089: pod2html: rev should be rel

[積丹尼 Dan Jacobson]

Package: perl
Version: 5.28.1-4
Severity: minor
File: /usr/bin/pod2html

$ pod2html /dev/null| tidy -eq
line 7 column 1 - Warning: <link> lacks "rel" attribute

So
<link rev="made" href="mailto:root at localhost" /> should be
<link rel="made" href="mailto:root at localhost" />

P.S.,
https://metacpan.org/pod/Pod::Html "Issues" leads to
https://rt.perl.org/ which doesn't have a "new bug" button, hence I
submit via Debian.

Oh and by the way the hardwired doctype in pod::html kind of dated
already... best to use HTML5 (thus without DTD dependency.)
