After the recent a38edab7c8 (Makefile: generate doc versions via
GIT-VERSION-GEN, 2024-12-06), building with Asciidoctor results in
manpages where the headers no longer contain "Git Manual" and the
footers no longer identify the built Git version.

Before a38edab7c8, we used to just provide a few attributes to
Asciidoctor (and asciidoc). Commit 7a30134358 (asciidoctor-extensions:
provide `<refmiscinfo/>`, 2019-09-16) noted that older versions of
Asciidoctor didn't propagate those attributes into the built XML files,
so we started injecting them ourselves from this script. With newer
versions of Asciidoctor, we'd end up with some harmless duplication
among the tags in the final XML.

Post-a38edab7c8, we don't provide these attributes and Asciidoctor
inserts empty-ish values. After our additions from 7a30134358, we get

  <refmiscinfo class="source">&#160;</refmiscinfo>
  <refmiscinfo class="manual">&#160;</refmiscinfo>
  <refmiscinfo class="source">2.47.1.[...]</refmiscinfo>
  <refmiscinfo class="manual">Git Manual</refmiscinfo>

When these are handled, it appears to be first come first served,
meaning that our additions have no effect and we regress as described in
the first paragraph.

Remove existing "source" or "manual" <refmiscinfo/> tags before adding
ours. I considered removing all <refmiscinfo/> to get a nice clean
slate, instead of just those two that we want to replace to be a bit
more precise. I opted for the latter. Maybe one day, Asciidoctor learns
to insert something useful there which `xmlto` can pick up and make good
use of -- let's not interfere.

Okay. So if I understand correctly, we used to have the exact same
values for those tags twice with newer versions of Asciidoctor, but
starting with the change we have one "empty" set of tags and one set of
tags that contain the replaced values. And because Asciidoctor ignores
the latter the end result is that we have empty ref info.

Okay, makes sense.

And this looks as expected.
