[IMP] crm: ask for loss reason in leads too

In odoo/odoo#118494 we made it possible to set a loss reason on a lead
from the list view action.

However this did not update the behavior of the form view button.

As we remove the 'set reason' suggestion in this PR (odoo/odoo#124103)
It makes sense to update the form action to behave
the same way as the list view one.
