Subject: [PATCH] [IMP] website_event_crm: set lang on event lead generation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Purpose: set `lang_id` and `visitor_ids` fields on leads generated by a lead
generation rule.

We check that there are several languages used on the website to make sure the
visitor's language is relevant. Then we propagate the visitor's language when
creating leads.

Task-3293050

closes odoo/odoo#124303
