[IMP] base_automation: default record_getter matches default webhook payload

The goal of this commit is to make it simpler for users to match an
incoming Odoo webhook automation rules with an outgoing webhook action
from another Odoo by having a default record_getter that uses the same
syntax as the default payload of a webhook action.
