Follow up to #11905.

When the active session is a notebook session, we want to show a "Change Notebook Session..." option in the interpreter picker list. This option will allow the user to change the environment the notebook is running against. This is the same exact action as the "Change Kernel..." option in the notebook kernel selector.

We want to update the quickpick shown when this action is fired to the one used by the "New Console Session..." action since its got a richer UI that organizes the sessions and provides a suggested option for users.

We should also take this time to rename the actions in the kernel selector menu:

• "Change Kernel..." -> "Change Notebook Session..."
• "Restart Kernel" -> "Restart Notebook Session"
• "Shutdown Kernel" -> "Shutdown Notebook Session"
