I was trying to do the exact same thing without git and coding (so that people could just view the bookmarks, maybe react to them as a voting mechanism). Ironically I ended up coding a solution for that - https://www.axomark.xyz .
The previous version was a free service without the need to sign up - just create a bookmark collection page with an optional password, then anyone with the password can use it right away. The link to the collection could be totally anonymous because the app tracked nothing at all. But I got 0 users, apart from myself. So I rewrote it from scratch to make the collections more organizable. The sharing is still anonymous because there's no way for another user to know who created them. There has to be a way, however to track your own bookmarks, so I guess it's not truly "anonymous" as in "impossible to track" (the database contains the bookmark owner). But it seemed this time around people are more interested. I guess there has to be a balance.
