fix(allow-db-explore): make that the set the allow-db-explore option

[prosdev0107]

SUMMARY

The "Allow this database to be explored" setting should be checked by default in the Database Connection UI

How to reproduce the bug

1. Create a new Database connection. (Google sheets is a quick one to create)
2. Expand the SQL Lab section under the ADVANCED tab, and make sure that Allow this database to be explored is disabled.
3. Save the connection.
4. However, the functionality is working as if the box was checked:
5. Navigate to SQL Lab > SQL Editor on the top navigation bar.
6. Execute a query on this newly connected database.
