[Breaking change] Migration 12.x -> 13.x breaks mailing list titles

Bug

Migration 12.x -> 13.x breaks mailing list titles

Environment

• Version: 13.0
• OS: Ubuntu 20 LXC
• Web server: Apache2
• PHP: PHP 7.4
• Database: MySQL 8
• URL(s): /comm/mailing/list.php?leftmenu=mailing

Expected and actual behavior

We should be able to see the titles in the list of mailing lists. After the migration, no titles are shown

Steps to reproduce the behavior

Upgrade from 12.x to 13.x

Possible remediations

Quick fix : In htdocs/comm/mailing/list.php, on line 241, replace $obj->title by $obj->titre (goes against the will of developers to translate variables in english)

Persistent fix : Change all references of m.titre in SQL queries and alter table llx_mailing with title instead of titre

Side note

I wouldn't mind creating a PR for this issue for a persistent fix however I am not sure of how database migrations are handled.
Is it directly in /htdocs/install/mysql/migration/12.0.0-13.0.0.sql ?
