Issue #3: Add a gitify rewrite for Alias /shared

As part of Koha "Bug 35716 - Duplicated assets in both koha-tmpl/intra-tmpl and koha-tmpl/opac-tmpl", we're going to need koha-gitify to rewrite a line in /etc/koha/apache-shared-opac.conf and in /etc/koha/apache-shared-intranet.conf

The line goes from: Alias /shared "/usr/share/koha/public/shared" To: Alias /shared "/kohadevbox/koha/public/shared"
