Refactor: Replace deprecated errorAndThrow with errorWithException

This PR updates the codebase to replace all usages of the deprecated errorAndThrow method with the recommended errorWithException method. Error messages are now wrapped in a new Error object for improved error handling and stack traces.

Details:

• Updated driver/lib/sessions/session.ts and driver/lib/sessions/observatory.ts to use this.log.errorWithException(new Error(...)) instead of this.log.errorAndThrow(...).
• No functional changes; this is a refactor to align with current logging and error-handling best practices.

Motivation:

• Removes usage of deprecated methods.
• Ensures better error stack traces and future compatibility.

• [nitpick] Consider passing the original error object (or including it as a property) to retain error context, which could be more helpful for debugging compared to a JSON string.

          this.log.errorWithException(new Error(JSON.stringify(e)));
