This seems to be due to using an environment variable inside flowy-server crate, which means the base_url is always the same unless the application is built by the self-hoster with preset environment variables.

We should of course set the base url according to the inputted self-host url, we can instead default it to the environment variable if none provided. (eg. in a small locally cached sqlite table containing the configuration).

The publish function of self-hosted appflowy also has a similar domain name problem. The domain name displayed after publish is appflowy.com
