[bug#75418] [PATCH] import: git: Do not search pre-release words in tag prefix.

[iyzsong--- via Guix-patches via <guix-patches@gnu.org>]

From: 宋文武 <iyzsong@member.fsf.org>

This fixes tags like 'xfce4-dev-tools-4.20.0'.

* tests/import-git.scm ("latest-git-tag-version: prefix contains pre-release
words"): New test.
* guix/import/git.scm (latest-tag): Don't filter out pre-releases tags.
(version-mapping): Filter out pre-releases tags from versions.
* gnu/packages/xfce.scm (garcon, thunar-archive-plugin, xfce4-dev-tools):
Remove FIXME comments for the 'generic-git' updater.
