Bug: missing mongo built-in schema

[wirelessr]

After using:

SHOW SCHEMAS in mongo;

The output is:

       Schema
--------------------
 information_schema

The root cause should be folder ./mongodb/database is missing, so the volumes is empty.

In fact, the latest trino can CREATE SCHEMA.
After using:

CREATE SCHEMA mongo.tiby;

The tiny can be built and used.

trino> SHOW SCHEMAS in mongo;

       Schema
--------------------
 information_schema
 tiny
