Reorganize monitoring package dependencies

The changes include some reorganization of the dependencies in the 'package.json' of the monitoring package and the web app, aimed to enhance readability. Also, a minor correction in the whitespace around "@sentry/nextjs" dependency version was made. Furthermore, code related to the monitoring instrumentation provider has been refactored for more readable error handling.
