fix(bank_rec): don't shadow Odoo's _() translation function in action_run_migration

Line 77 was `_ = super().action_run_migration()`, using `_` as a
throwaway variable name. That rebinds the module-level `_` (Odoo's
translation function imported at the top) to whatever super() returns
\u2014 in our case the parent's notification dict.

Lines 84/85 then call `_('Bank-Rec Migration Complete')` which is
now `some_dict('Bank-Rec Migration Complete')` \u2192
TypeError: 'dict' object is not callable.

User hit this when running the migration wizard from the menu.

Fix: drop the assignment; we don't actually use super()'s return value.
