upgrade-ir-default-get (U1718)

ir.default.get(), renamed _get() in Odoo 17.0.

Applies to Odoo 17.0 and later.

What it does

Reports self.env["ir.default"].get(...).

Why is this bad?

Odoo 17.0 removed the public get (deprecated in 16.0): the call raises AttributeError.

Fix safety

Safe: get becomes _get, with the same arguments.
