[16.0][IMP] Update template from copier + [FIX] rma: rma.order.line code in single file

[AaronHForgeFlow]

Try to make pre-commit green

[AaronHForgeFlow]

Will not be green until copier is updated with latest changes in OCA/oca-addons-repo-template#214

[AaronHForgeFlow]

Can't wait for the merge in that PR. Just forcing the python version to 3.11 in pre-commit.
