[REM] l10n_fr: duplicate method (_prepare_all_journals)

defined first 4y ago in https://github.com/odoo/odoo/commit/d56baebc8e7f654304eca59b3c58ceb80846c659
then 2y ago in https://github.com/odoo/odoo/commit/182b4d86f443eefcc647fb44f0b1f5fe406637d4

Merge the two methods, keeping the one in the dedicated account_chart_template file,
but improving it with the early check on the company country code.

Fixes #67728

closes odoo/odoo#67882
