[FIX] l10n_sa: remove duplicate xmlid in translations

Module was not installable in some circumstances

To reproduce:
- Make Arabic and Arabic (Syria) languages active
- Try installing l10n_sa
==> crash: "psycopg2.errors.CardinalityViolation: ON CONFLICT DO UPDATE command cannot affect row a second time"

This was due to duplicate xmlid in the translation file.

closes odoo/odoo#78411
