fix: prevent deletion of active connection secrets when updating note…

[Gkrumbach07]

https://issues.redhat.com/browse/RHOAIENG-15228

Description

The system incorrectly deletes active connection secrets when updating notebook environment variables, potentially causing disruption to running connections.

How Has This Been Tested?

1. Create a notebook with environment variables
2. Set up an connection to a data connection
3. Set up other connection types as well (turn dat feature flag on)
4. save
5. edit
6. Observe that the active connection secrets are not incorrectly deleted and the warning message is not there
