Is there a page like https://translate.techreborn.ovh/ for translate the RebornCore?

I think it could be good to have also a page in Crowdin for RebornCore the same way it is for TechReborn. Although this has less text, translating it through Crowdin helps to maintain it synchronized and visualize the progress.

Consider Weblate instead, see jitsi/jitsi-meet#5056 (comment)
Happy to help.
