the v2 old site (https://github.com/casbin/casbin-website-v3) uses docusaurus and already has a Crowdin project: https://crowdin.com/project/casbin

now for this fumadocs v3 site (https://github.com/casbin/casbin-website-v3), better to use the same Crowdin project (and existing transations) to enable i18n in this v3 site
