Explain the details for making this change. What existing problem does the pull request solve?

The create-site uses the deprecated --no-mariadb-socket command line argument.
Using the recommended --mariadb-user-host-login-scope='%' has been tested successfully

error message: --no-mariadb-socket is DEPRECATED; use --mariadb-user-host-login-scope='%' (wildcard) or --mariadb-user-host-login-scope=, instead. The name of this option was misleading: it had nothing to do with sockets.

if i'm not mistaken, this would break v14 and earlier deployments, if any, unless, we drop support for those versions, which idk if it's unlikely or not.
