Update Mongoose to Avoid Deprecation Warning
The deprecation warning is likely due to the use of outdated Mongoose methods or options that are no longer supported in the current version of MongoDB or Mongoose. This can happen when using features that have been replaced or removed in newer releases, leading to compatibility issues.
