Support odoo>=18.0

Avoid logging error/warning on: fix 2/3 topic of #79 (you needs this PR to make is works https://github.com/odoo/odoo/pull/184409)

• In odoo 18 if we load odoo.tests.common before setting test_enable=True we get a logging error which is very noisy while developing. ie :

pytest --odoo-database db-test odoo/addons/ --ff --sw
Importing test framework, avoid importing from business modules and when not running in test mode

• second point is a warning displayed while opening the registry

 /.venv/lib/python3.12/site-packages/pytest_odoo.py:167: DeprecationWarning: Use directly odoo.modules.registry.Registry
    odoo.registry(db_name)

because this registry method becomes deprecated https://github.com/odoo/odoo/blob/18.0/odoo/init.py#L37 we can safely use the Registry as this method do because we are setting the database and this code hasn't change from odoo v10.0
