[FIX] sale: show payment term note on customer portal preview

Description:
There is a discrepancy between the printed sale order report and the
customer preview when it comes to displaying the Payment Terms. On the
SO report, Odoo prints the 'note' field, whereas on the preview, Odoo
only displays the 'name' field.

Desired behavior after PR is merged:
Customer preview now matches the printed report by displaying the
payment_term.note field as well
