Update SDK key validation in NodeJS

CHANGES.txt

@@ -6,6 +6,7 @@
     - Added a new optional Split Filter configuration option. This allows the SDK and Split services to only synchronize the flags in the specified flag sets, avoiding unused or unwanted flags from being synced on the SDK instance, bringing all the benefits from a reduced payload.
       - Note: Only applicable when the SDK is in charge of the rollout data synchronization. When not applicable, the SDK will log a warning on init.
     - Added `sets` property to the `SplitView` object returned by the `split` and `splits` methods of the SDK manager to expose flag sets on flag views.
+  - Bugfixing - Fixed SDK key validation in NodeJS to ensure the SDK_READY_TIMED_OUT event is emitted when a client-side type SDK key is provided instead of a server-side one (Related to issue https://github.com/splitio/javascript-client/issues/768).
 
 1.10.0 (October 20, 2023)
  - Added `defaultTreatment` property to the `SplitView` object returned by the `split` and `splits` methods of the SDK manager (Related to issue https://github.com/splitio/javascript-commons/issues/225).
