[FIX] website_event: add missing ir.model.access

There isn't `ir.model.access` on `event.event.ticket` for public and
portal users, but there is already the `ir.rule` to check the access.

In master, It causes an issue now, since https://github.com/odoo/odoo/pull/82896,
the `description` field of `event.event.ticket` isn't prefetch anymore
by the sudoed `event_registrations_open`
compute (that fill the cache with ticket data in sudo).
It crashes single app build:
https://runbot.odoo.com/runbot/build/12473674

We prefer to backport it in stable, there are maybe some corners where
it will raise an Exception and for sake of correctness.

closes odoo/odoo#84072
