[pacman-dev] [PATCH] doc: use localdate instead of pacman_date to improve reproducibility

[Jonas Witschel]

pacman_date is set to the current date during build without respecting
SOURCE_DATE_EPOCH. As a result, a build cannot be fully reproduced on a later
date because the date embedded into the man pages does not match.

In contrast, the built-in asciidoc attribute "localdate" respects
SOURCE_DATE_EPOCH and has the desired ISO 8601 format, so simply use that
instead of the custom "pacman_date" attribute.

Fixes: FS#71154
