[bugfix] update the default configuration to not set a db type or address, to require explicitly setting it (#4228)

This updates the database defaults to remove a type or address. This is to help ensure we don't have any repeats of https://codeberg.org/superseriousbusiness/gotosocial/issues/4183, it means the user needs to explicitly configure these things core settings instead of relying on defaults.
