This update moves a key test case related to UBL (Universal Business Language) billing in Belgium (account_edi_ubl_cii) to the new testing framework. This ensures better test coverage and reliability for our UBL billing processes, improving the overall quality of the system. The change was prompted by a previous update to the test suite.

Move test introduced by https://github.com/odoo/odoo/pull/265261 to the new test suite in account_edi_ubl_cii
