Following task-5364749, we noticed there were some industries like art_craft that are creating their POS configs and journals manually, which is probably error prone and will create unwanted behaviors like duplicate account journals. Instead, we should call a function to load a scenario and modify the existing data.
Furthermore, thanks to this commit odoo/odoo#244246, we can, from the data that is being imported, infer whether or not the module is loaded with demo. Therefore, we can call, from the data, the
load_onboarding_scenariofunctions with the additional parameterwith_demo_dataasTrueorFalseto load the scenario's default demo data in one go.NB: at the moment, the retail scenario has no demo data that come with the function call, but the parameter still exists. The kiosk scenario however has no demo data parameter.
