Exposure of interface sensitive information

[Aterl]

🐛 Bug Report

When I deploy supertokens core using self host mode, the database uses MySQL. After starting supertokens core and shutting down the MySQL service, accessing the supertokens core deployment port will expose the MySQL user password in the configuration file to the outside world.

This will cause data security issues when continuing to start the MySQL service in the future. How to deal with this problem.

supertokens-core version：9.3.0
