upgrade-norecompute (U1717)

env.norecompute(), a no-op since Odoo 17.0.

Applies to Odoo 17.0 and later.

What it does

Reports norecompute() calls.

Why is this bad?

Odoo 17.0 made it a deprecated no-op: code relying on it to delay recomputations no longer does. Remove the with and keep its body.
