[FIX] stock: allow to create new picking type to non-admin users

Before this commit, Inventory Admin was not able to create new /edit picking type
as Non-admin users doesn't have rights to create/edit sequence.

With this commit, we are creating/editing `sequence_id` with sudo

closes odoo/odoo#75606
